Botzu's Quick Evaluation

+ Trait: Arts damage that bounces to multiple enemies and slows them. Damage is reduced with each bounce
+ Talent: Increases damage against unblocked enemies
+ S2: ATK increases, damage no longer reduced for bounces. Great DPS if bounces can be utilized
+ A good slowing and damage option for no-block strategies and teamed up with other slowing and crowd-control Operators
= She is a middle ground between an AoE and ST Caster. She is only better than an AoE Caster when enemies are too far apart for the AoE splash, and is only better than an ST Caster when multiple enemies are close enough for the bounce.
= Attack Interval is faster than an AoE Caster but slower than an ST Caster
- High DP cost
- Low base ATK
- Bounce range is only 1 grid and cannot bounce to previously hit targets

Operator Overview

Leizi is determined to help Rhodes Island, but as a government official, her mere presence threatens to throw Rhodes Island’s careful political neutrality out of balance. Despite this, she insists on wielding her powerful Originium Arts as a 5 Caster. What kind of Caster? Well, Leizi is technically single-target, but in practice she hits multiple targets due to her Trait, which causes her lightning Arts to “bounce” between enemies (and Slow them!) at the cost of reducing the damage dealt to each subsequent target in the chain.

This Kirin Caster capitalizes on her Trait using her Talent, Unobstructed Flow, which increases her ATK against targets who are not being Blocked. This, combined with the slowing effect on her attacks, makes her great for no-Block strategies. Since Leizi’s attacks can travel up a line of advancing enemies, she can easily hit multiple unblocked enemies if they are close enough together. Her damage is increased even further with her Skill 2, Thunderclap, which massively increases her ATK and causes her attacks to deal full damage no matter how many times they bounce. Unfortunately, Thunderclap has an extremely high SP cost and only an average duration, so Leizi doesn’t get many chances to unleash her full power on a given map.

Leizi occupies an interesting middle ground between ST Casters and AoE Casters. If enemies are spread too far apart for her chain lightning to connect, then a ST Caster is more efficient. On the other hand, if enough enemies are bunched up in a group, a true AoE Caster is more efficient. Her high DP cost and the poor uptime on Thunderclap can further hamper her usefulness. However, with the attack range of a ST Caster and faster attack speed than an AoE Caster, Leizi’s damage potential is quite high when her chains can be strung together properly. She is especially well-suited for a no-Block strategy, where her Talent is always active and her Slow can keep advancing enemies at the proper range for mass electrocution.

Newbie Tier List Explanation

Fairly weak at low development and requires heavy investment to shine. Not worth raising early.

Skill Discussion

S2M3 A- * B * B+ *

* Note that these skills are graded assuming the unit has her CHA-X Module at least level 2. If you do NOT plan to get this unit's upgraded Module, treat the priority of these skills significantly lower.

Leizi has spent many years loitering at the very bottom of the meta. Her 80 SP cost made her unusable despite decent skill up damage. However, in rare form, Hypergryph actually gave Leizi a Module upgrade that addresses her core issue in a big way. At Module level 2, she gains 1 SP per bounce (not per attack) which makes a huge dent in that otherwise abhorrent downtime. While being reliant on a constant flow of unblocked enemies makes her somewhat unreliable, it also lets her shine in some circumstances with a ridiculously high uptime on good damage and solid control. In SSS, she is especially ridiculous and is one of the top “carry” picks, despite her rarity. Keep in mind that Leizi’s S2 Masteries provide a well above average amount of ATK, so her grades are a touch higher than her overall value. The 5★ Caster group is a crowded and dubious set, but Leizi is one of the few that manages to stand-out… if you’re willing to go the extra mile with investment anyway.

While ungraded, S1 may be worth considering as well if you plan to maximize your Leizi usage. Although it has significantly less damage, it can have really ridiculous uptime thanks to her Module.

Module Analysis

Operator Impact: Low/No

Meta Use: Low

Explanation:  The Slow improvement brings it in line with Slower Supporters, which is nice, but her longer ASPD reduces her Slowing effectiveness and there is nothing in her kit to take better advantage of it.  Leizi's S2 already eliminates the jump damage reduction, rendering that part of the Module useless during Skill duration.

Leizi, an official from Yan's Central Judicial Office, is temporarily residing in Rhodes Island after signing an investigation agreement. Well-trained in combat skills and possessing unique Originium Arts, Leizi excels in annihilation battles and positional warfare. However, because of her noteworthy background and ambiguous motives, it is recommended to err on the side of a passive, non-cooperative tone when communicating with her.

Clinical Analysis

[Originium Arts Overview] 'Lei Fa' is a technique spreading through Yan that focuses on the manipulation of electricity. Many mature schools of Originium Arts share similar methods of inheritance - for example, Leithanians use movements, the Sarkaz lead through ceremonies, and various guilds of Arts practitioners conduct research, all for the purpose of passing down the theoretical and practical components of Originium Arts. As one of the traditional Originium Arts originating from Yan, Lei Fa has a deeper history than most other forms of Arts. As a system shrouded in mysticism, the requirements for practitioners of Lei Fa are also restrictive and physically demanding. Its inheritance system gradually evolved into a solemn ritual of sorts, much like the passage of power. The end result was that Lei Fa tacitly became synonymous with the position of power, subsuming the popular symbol of law enforcement, and even becoming a form of self-cultivation in the quest for spiritual transcendence. As for rumors of the physical basis of 'transcendence,' I can only say that as an Originium Arts researcher outside of Yan's cultural circles... I must harbor a healthy amount of skepticism.
Obviously, Leizi exhibits a degree of pride for the Arts she uses.
According to some officials, when she taps into her powerful Originium Arts, her hair will become very smooth. Though I don't know why, I can scarcely imagine anything more worth investigating...

I must question your priorities...

[First Record] Leizi's official background is enough to keep the entirety of Rhodes Island awake at night. To be honest, the whole reason Rhodes Island is able to survive the tempestuous conflicts among various city-states is that in addition to the confidentiality and necessity of our line of work, maintaining political neutrality is essential. This is accomplished by balancing the benefits afforded to different city-states, negotiating with government representatives, and trading favors - and although these actions are necessary for the survival of Rhodes Island, the less we have to do, the better. An empire's government officials appearing on board Rhodes Island's ship, regardless of their position or rank, is almost always a dangerous matter. The fact that she even requested a long-term stay cannot possibly spell out good news for us.

[Fourth Record]
Dobermann suddenly told me that Leizi had actually already been on board for three months. I took the news calmly, about as calmly as a someone trying to disarm a time bomb that would explode and take out half of the entire city in just three seconds being told that their daughter had just run away from Columbia's terminally ill Ursusian military police.
Not disclosing an operator's background is just ignoring the problem, but hiding it from the entire ship is just ludicrous. No amount of paper can contain a fire, and no matter who made this decision, this is definitely a bad move.
Someone with years of intensive training, representing a major political playmaker, is now walking around freely on the ship... The grim reaper would not lie to you when asked why it has come, but this woman would not leak a hint of why she's here even if starved for three days. What are we supposed to do?
What?! She even applied to join an operational squad? And it was approved?!
Ughh... My stomach hurts and I want to resign from the HR Department and go home.
Dobermann's smiling at me with a look of resignation on her face. Whatever, how odd that a she can smile like that at a time like this.

[Sixth Record]
We consider ourselves lucky.
Some Operators, such as Skadi or Shining, don't seem to care at all about this issue. The fact that they can focus on their goals and practically ignore all the rest of the background noise is good for their work.
Some others are concerned, but are just keeping silent about the matter. For example, Ansel brought up the issue several times, but decided against it each time and left after dropping off some snacks. They've struck a good balance between curiosity and their sense of responsibility.
Or, they simply don't know anything about it. I once witnessed Cuora getting lost and ending up in front of Leizi's dorm, only to have dinner with her before being sent back to Block A. Cuora will recount how they had four main dishes that night as well as a soup, concluding that Leizi is a very nice person, end of story.
Yet another type is those who have already been bound up and silenced, not even uttering a word about the matter even if tortured. Yesterday, I caught Blaze slacking off while I was on duty. Even though this time it was basically just bureaucratic busywork, and Blaze tends to use this time to get some rest and relaxation, she actually ran over to the intelligence room to go over files with the person who complains most often about her work ethic - Leizi. Amiya, who was standing at the doorway, even vouched for them before apologizing to me and pushing me out. She still had that faint smile as she waved me goodbye.
Some of us are definitely going crazy, and I've begun to suspect that it's actually me. Having that said, this proves that in addition to gathering data, Leizi has a vested interest in 'maintaining amicable relationships with her targets.' While it's true that she hasn't done anything yet, she also has been concealing her whereabouts from the rest of the world.
At first, I interpreted her application for long-term board as a form of rhetoric. In that regard, I admit I was in the wrong. It's just that to write this whole thing off as 'improving relationships' is far too suspicious.
How ironic. Concealment and deceit have turned into a method of expressing trust, and turning a blind eye in order to coexist together has become the new norm.
Fortunately, the great powers have not turned their gaze upon Rhodes Island just yet, a neglect which has already saved us several times.
Of course, if she was trying to spy on us, it would be stupid to walk in with an official state-sponsored identity. But that is precisely why we cannot rule out the possibility, and must do our best to maintain confidentiality and control the information going out.

To be honest, she is very good at her job. A pity that she is not one of our Operators.
I can actually make some inferences about what happened to her before, and it's entirely understandable why she seems to be in a rather odd state.
Perhaps now, the only proof of her true self is that tone of voice, and her golden locks that flow like electricity. I believe that she is in a self-imposed exile as a result of this case.
No matter where you are, there is a price to be paid for being selfless. If you fully dive into this cause, you will also give up your future. However, now that I think about it, surely the Central Judicial Office has no shortage of such personnel?

I admire her courage and perseverance fleeing here by herself. That would be a reason to shelter her even if she didn't pull her weight.
The hardships that she must endure from here on out, and the path that she must take, may yet be unknown to her still. No, I'm sure she knows full well, but simply has chosen not to act upon it.
Some people believe that those who work in the judiciary have a strong moral compass, and everyone can see that on display. In Leizi's case, she readily apologizes if she is wrong, and never toots her horn when she is right. You will never be able to get someone like her to stop bowing her head. It's a part of who she is.

Despite her many virtues, a glaring blemish is her attitude towards the Infected. By the looks of things, this is not something that can be changed in a short time.
However, just as day and night eventually blend together, I trust that a day will come when she understands the plight of the Infected. After all, she needs our help as well. I heard that Leizi spoke of a certain time in Yan, or a certain season... something involving the spring's first roar of thunder. The spring thunder is supposed to penetrate the darkness of the long winter.
I'll look after her, provided I don't get pissed off to all hell by those who are keenly interested in her personal belongings, like Haze and Rope.

Voice Lines

Appointed as Assistant Look carefully. The files are sorted by type, then time limit prioritization, then finally, by distance from nearest to farthest. This is the most efficient organization method! ...Wait, I seem to have done all the paperwork on accident. This... is supposed to be your job, right?
Talk 1 I've checked all files related to the elite Operator, Blaze, and there are no records of her real name, or place and date of birth. Don't tell me you don't know; aren't you supposed to be one of the leaders here? You really don't know? Then... nevermind. Sorry, I shouldn't have accused you.
Talk 2 You don't need to be so cautious around me. Other than the case at hand, I'll treat everything else on the ship as if it never happened. But if there's another explosion in the hallway outside my room, I'll make the perpetrator's hair stand on end for two weeks!
Talk 3 'Assume the responsibilities for the post to which you are assigned.' As one of the leaders of Rhodes Island, is it not your duty to... Huh? My hair's standing up again? Hold on! G-give me a moment to fix my look first! Weird, I thought I had discharged all the static electricity this morning...
Talk after Promotion 1 Even today, I can vaguely recall the first time I saw you in Lungmen. You, Blaze, and Ch'en... are all holding onto countless secrets... and I will uncover them one by one. You're willing to exchange secrets? Wait, y-you... it's t-too early for that...!
Talk after Promotion 2 Ask me anything. Only when you speak up can I decide what is just and unjust, and whether I wish to take action. I need to take my identity into consideration? This has nothing to do with that! The Censorate, Central Judicial Office, and the Department of Discipline and Supervision... are only institutions. Laws can only be proven just when enforced by someone.
Talk after Trust Increase 1 Rhodes Island's ideals conflict with my beliefs. However, I do recognize the necessity of seeking common ground while understanding our differences... The same is true when providing assistance in exchange for information.
Talk after Trust Increase 2 No matter where I am, the electricity flowing through my body never ceases. The thunderbolt is the symbol of justice; it drives me forward and sometimes even wakes me up at night... Someone is complaining that I broke the AC unit? ...How rude! How is that possible?! I don't even need to use a remote for the AC, let alone touch it!
Talk after Trust Increase 3 Blaze was implicated in a major incident. All the clues have purposely been eliminated, but I have my doubts about the way the facts of the case are connected based upon a few coincidences between certain persons and times. This has nothing to do with you, but you should take adequate precautions. All I can do is offer you a fair warning.
Idle You can't even properly manage your physical condition... how slovenly! Look at you sprawled out like this... Were you waiting for me to put a blanket over you or something? ...There won't be a next time.
Onboard I've signed obtained an investigation authorization with your company. Don't worry about it, this is purely over personal matters. If you so wish, you may call me Leizi. Who am I? Have we met before? Are you serious?!
Watching Battle Record I see, this is a completely different principle from military training.
Promotion 1 Elite status? Is this... a promotion? The promotion process at Rhodes Island seems to differ from that of ordinary private companies...
Promotion 2 I, Leizi, am the bearer of the thunder and the law, the vision and reach of Great Yan. My philosophy does not align with that of Rhodes Island, and I have no intention on bridging the gap between the Infected and non-Infected. However, we can now fight side by side against our enemies!
Added to Squad With my own eyes, I shall judge what power Rhodes Island possesses.
Appointed as Squad Leader I can do that, yes, albeit at a price.
