Botzu's Quick Evaluation

+ High base ATK, and with great ATK buff from S2 she can reach over 2k ATK when maxed
+ Her HP is monstrous, and combined with S1 she is very durable
+ Can scale to endgame
= Duelist type Block-1
- Weaker than Melantha at the same levels
- The farther you get into the game, the less you will need a dedicated guard to fight enemy Casters
- Many higher rarity Guard options.

Operator Overview

“You don't even recognize me on the battlefield? I just start cutting through enemies one by one with a blank expression on my face? Wow! Sounds hella badass! Wish I could watch myself out there.”

Off the battlefield, Matoimaru is a hyper-cheerful ball of energy who indulges in sparring matches, soccer games, and flower arrangements (on display every Saturday at 3pm!). On the battlefield, she is a stone-cold 4* Duelist Guard designed for single-target assassination.

Matoimaru is a rather lopsided Operator who has put all of her stats into HP and ATK, completely neglecting DEF. Her E2 Talent, Demonic Physique, passively increases her HP and lowers her DEF, and both of her Skills play into this dichotomy further. Her Skill 1, Regeneration β, is a simple self-heal that gives Matoimaru incredible self-sustain. When you need her to cut loose and kill everything, use her Skill 2, Demonic Power, which offers a crazy ATK boost in exchange for lowering her DEF to 0 for the Skill duration.

Dropping to 0 DEF can be an issue for an Operator like Matoimaru. With Demonic Power active, engaging the wrong opponent or being in range of one extra ranged unit can swiftly lead to her death. However, if you don’t overextend her, Matoimaru’s deep HP pool can absorb quite a few hits. And of course, her lack of DEF is no problem at all when it comes to killing enemy Casters. In fact, her huge HP pool and quick-charging Skills make it easy for her to tank a few magic bolts while she’s cutting a key enemy Caster to ribbons.

Base Skill Analysis

Mato gains her second RIIC Skill at E1.

Is it worth it?  Probably.  This is one of the best possible Trading Post buffs, so unless the player is already running their Trading Posts full-time with Ops buffing as much or more, then Mato is a good Promote.

Profile

This nomadic warrior from the Far East joined Rhodes Island by sheer chance.

Matoimaru is a magnificent warrior from the Far East.
She is simpleminded and prone to deception. She does catch on, but a new trick will fool her again.
Her hobbies, at which she excels, are sparring, soccer, and floral arrangement. She has been known to organize events around these subjects, though her idea of organization is typically dragging people kicking and screaming into it.

Archive File 2

Increase Trust to 100.
The Oni are still a mystery to most people. Aside from living in the Far East, there seems to be little in common among the race.
However, Matoimaru is yet even more different from other Oni: Her bloodlust makes her performance on the battlefield strikingly unique, though it seems she's not aware of this fact.

Archive File 3

Increase Trust to 150.
Many Operators think Matoimaru is crude and unrefined, but they are mistaken.
They just need to check out her floral arrangements, on display every Saturday at 3pm.
The beauty she can create is positively astonishing.

Archive File 4

Increase Trust to 200.
Matoimaru is obviously self-conscious about her flaws: She is not good at controlling her strength or at critical thinking.
She took up floral arrangement to refine herself and to show the others they don't need to fear her.
Despite this, she's remains quite gullible. At least she has learned to question the idea that she must be a great thinker in order to survive.
As far as she is concerned, her ideal companion would be someone who won't deceive or betray her, and will stay with her and guide her. How wonderful that would be...

Appointed as Assistant Doctor, you gotta be hungry! Try some of my onigiri. They're great!
Talk 1 I've actually got a lotta hobbies. They go way beyond martial arts. I'm also really into soccer, and flower arrangement. Wouldn't want you thinking I'm just some kinda bloodthirsty monster!
Talk 2 My race eats other races? That's some old crap! Who told you that? Pff, what kinda coward goes around talking that crap behind my back? I'll give 'em a peace of my mind when I find 'em.
Talk 3 My body? Heals right up whenever I get hurt. Even in the middle of a fight, the wounds close right back up. Handy, huh.
Talk after Promotion 1 Hey, Doctor, Rhodes Island's got a soccer tournament! Let's sign up together. When you got me on your team, it's in the bag, don't worry. Doctor, you better start thinking up a cool victory pose!
Talk after Promotion 2 You don't even recognize me on the battlefield? I just start cutting through enemies one by one with a blank expression on my face? Wow! Sounds hella badass! Wish I could watch myself out there.
Talk after Trust Increase 1 I got this problem where I kinda end up breaking stuff, so I'm working with my flower arrangement teacher to control my strength. Being around all those pretty flowers makes me real happy too.
Talk after Trust Increase 2 Strategy? Ehh, not really my specialty. That's why I keep hopping right into the enemy's plans. But with you, Doctor, you always stop me before I screw up too bad. Been a big help!
Talk after Trust Increase 3 I've always been pretty gullible. It's almost gotten me killed. But now I, Matoimaru, swear loyalty to you, Doctor! I know you'll never betray me, Doctor!
