Naga-ame
Expand
Naga-ame (a Touhou LW original) refers to rainfall that lasts for a long time. When it rains for days on end, it is the perfect time to read books, which makes this temperament a good fit for the face of the Suzunaan book rental shop. Kosuzu is endowed with Wood Phase, as she works in a bookstore, and Star Essence, with her highly curious personality.

The strong and kind Wood Phase resists Water Phase, because water nourishes wood, but it is weak to Metal Phase, because metal carves wood.

The diverse and uncooperative Star Essence resists the cooperative and indecisive Moon Essence, but it is weak to the charming and arrogant Sun Essence.

Info
Kosuzu Motoori's Focus Shot (a Touhou LW original). An attack that summons the shadow of an evil young dragon. Although it's small, a dragon is still a dragon and should not be underestimated. It seems that a fair amount of magic is contained within this print.

Bullet Info
Kosuzu Motoori's Spell Card (a Touhou LW original). She unleashes this attack by borrowing the power stored in a mysterious history book. Opinion is divided on whether this document, written with mysterious characters that are said to have been used in ancient Japan, can actually be called a history book or not. Nevertheless, it is most definitely a document that borders the line between fantasy and reality.

Bullet Info
Kosuzu Motoori's Last Word (a Touhou LW original). This attack summons the shadow of an extremely large tsukumogami. Kosuzu barely remembers anything of the time when she was possessed by this particular tsukumogami. Mamizou was apparently the one who returned this scroll to her, though it is unclear whether this is the original or an exquisitely crafted forgery...

Character Ability

Capable of reading any language
Expand
Kosuzu Motoori is capable of reading any language, even languages used by youkai, as long as the text is made up of symbols that can be perceived as letters or characters. Consequently she can read any and all demon books. There seems to be no limit to the type or amount of languages that she can read. She has been seen reading a demon book written in the ancient tengu language and Suzunaan deals with handwritten copies of magic books from the outside. However, even if the symbols on a text are in fact letters, Kosuzu can only read it if she herself recognises that these symbols are a form of letters or characters. Her ability appears to still be evolving as she has gained the capability to sense the aura of books. This may or may not be related to Kosuzu's ability, but in the outside world there is a peculiar theory that recorded information could be transformed into energy. If this is true, it may mean that every book is imbued with some sort of magic...
For every layer of Barrier Status: Poison & Blind, Yang ATK, Yin ATK, CRIT ATK, & CRIT Accuracy 1 level UP.

Character Analysis

“Well, we’ll cross that bridge when we come to it!”

The Bibliophile with a Deciphering Eye, Kosuzu Motoori works at a bookshop in the Human Village named Suzunaan. Whilst it primarily sells and rents books that have drifted in from the outside world, Kosuzu herself is far more intrigued by youma books - that is, anything written by a youkai. Between this and her interest in youkai as a whole, she’s certainly an atypical human. One who’s willing to dive headfirst into battles of bullets, backing you up as an A Tier Friend.

For farming, Kosuzu’s primary use is for farming Chapter 2-7-1 on Lunatic, as her Piercing damage (that is, it will ignore DEF Up) Last Word will bypass Marisa’s DEF Up. Do keep in mind that she will need proper teammates - one popular composition is Kosuzu, Toyohime, and a buffer such as Akyuu. Outside of this, Kosuzu’s damage is somewhat low for 1 Turn, and she’s not very well suited to farming Events by herself.

For harder stages, Kosuzu’s primary use is once again in the form of her Piercing damage on her All targeting Last Word. As numerous hard fights include numerous levels of DEF Up, it’s certainly a valuable asset. However, this is let down by a few things: Firstly, Kosuzu herself is somewhat lacking in ATK Up, alongside having a serviceable but not particularly high Yin ATK. Her Accuracy is also rather low. Additionally, the Piercing is only on the first and second bullet lines of her Last Word - whilst this still makes up a majority of its damage, it does somewhat put a damper on how effective her Piercing is. Lastly, Piercing itself is unfortunately virtually non-existent on Last Words outside of Kosuzu’s. All of this put together means that Kosuzu will typically need assistance to complete a stage, which means your other attackers will need to somehow deal with the DEF Up themselves, which means her Piercing, whilst still useful, ultimately isn’t as attractive as it initially seems.

Outside of this, Kosuzu has some team utility as well. Both of her Spell Cards pack an average amount of Breaks, at 1/2/3 Wood or Water Breaks for 0/1/2 Spirit Power, for her first and second Spell Card respectively. Additionally, her first Spell Card also packs 2 Levels of CRI Evasion DOWN for all targets for 3 turns, which combined with her above-average Crit rate makes her a nice addition to Crit heavy teams. Do keep in mind however that her second Spell Card has considerable Rebound on it, and she may need some help if you want her to stay around after using it.

Here are the chances for Kosuzu’s secondary effects (per bullet):

Flying Book: The 6th Vision of Zechariah: Chance for CRIT Eva UP 0%/0%/0%/100%/0%/100%

Original Text: Hotsuma Tsutae: Consumes HP 10%/0%/10%/0%/10%/0%

Chance for Yin ATK UP 0%/0%/100%/0%/100%/0%

Privately Published Night Parade Scroll - Final Chapter Annex: Consumes HP 30%/0%/0%/0%/0%/0%

Story Card Recommendations

Spell Card

Which Story Cards you use on Kosuzu’s Spell Cards will depend on her role in the fight. If you’re bringing her for Breaks, she’ll want to use Spirit Power granting Spell cards like Witch of Scarlet Dreams, as she has no special means of Spirit Power generation. Alternatively, if using her simply for her Last Word’s damage, you’ll want to favor Story Cards which provide Yin ATK Up such as Overwhelming Firepower.

Last Word

With Kosuzu’s extremely low Accuracy, there’s no way around using a Story Card which provides 3 Levels of Accuracy Up, such as a MLB Valued Tools of the Trade. If you can provide her with external Accuracy support, then you can look to a Story Card which boosts Yin ATK instead, such as Overwhelming Firepower.

Character Skill Level Up Recommendations

None of Kosuzu's skills affect her ability to farm Chapter 2-7, so you can safely skip leveling them if that's all you care about. Otherwise, Ancient Tengu Book should be leveled first, as it provides the best return on investment. Next, Read Demon Books provides somewhat low returns due to the random nature of crit and only giving a 50% chance for another Acc stage at max, but it's better than nothing. Finally, Customer Attraction gains almost nothing from additional levels, and can be safely saved for after you're out of other characters to train, as you'll likely never use it.

Character Strengths

+Last Word deals a lot of Piercing damage
+Average access to Water and Wood Breaks, at 1/2/3 Breaks for 0/1/2 Spirit Power
+Some Cri EVA DOWN Support for teammates

Character Weaknesses

-Second Spell Card deals self-damage to Kosuzu
-Her Piercing isn't as good as you'd think
-Overall low damage output outside of Piercing shenanigans without heavy setup
