Harugasumi
Expand
Harugasumi (a Touhou LW original) refers to the haze that appears in the spring. It is similar to Hanagumori, Patchouli's temperament, and the way this temperament blocks out the sun is very apt for a member of the Scarlet Devil Mansion. Just like Patchouli, Koakuma's Phase and Essence endowments are a little unusual.

As a denizen of the dark and a magical being, Koakuma is strong against Star Essence and Moon Essence. On the other hand, she is weak to Sun Essence and Fire Phase, which are considered holy symbols in foreign lands to the west.

Koakuma's Spread Shot (a Touhou LW original). This attack references a record written on a certain stone tablet. This tablet is in the mansion's library and is one of Koakuma's favorites. Apparently, she enjoys reading other people's secrets.

Koakuma's Spell Card (a Touhou LW original). She rushes forward and pulverizes everything. Apparently, she throws a barrier up around her head and headbutts with all her strength... A brain trained on books is a frightful thing if Koakuma can cause this much damage with only her head.

Koakuma's Last Word (a Touhou LW original). She uses a book connected to a parallel world (or so the rumors go, though there is no proof of this) to seal her target in the gap between dimensions... But Koakuma's magic power cannot actually go that far, so the damage caused is limited. That said, it is impossible to imagine someone who could actually use this attack to the fullest...

Character Ability

- Ability Unknown -
Expand
Koakuma's ability is unknown. As she is a devil, she is obviously good at magic, but it is unclear what kind of magic she specializes in and how her magic differs from the magic of the Scarlet sisters, who are also categorized as devils. Whether or not she was summoned by Patchouli is a mystery, but the relationship between the two would suggest she was. Her title is the Nameless Little Devil (a Touhou LW original) because nobody knows her actual name. She is only called Koakuma (literally meaning little devil in Japanese) because it is the name of a weak race of demons.
When inflicted by Barrier Status: Burn or Freeze, inflicts the same Barrier Status to target.

Character Analysis

Koakuma was released on October 29th, 2021 in "Prayer: Little Devil & Little Darkness." For more up-to-date analysis, be sure to visit the Discord Official Discord Server.

Koakuma is a devil without a name - even the nickname she’s been given by fans (and is by now pseudo-official) means “Little Devil.” Originally a midboss in Embodiment of Scarlet Devil, all she had was a sprite - but in those early days of Touhou mania, with so few characters to go around, people were more than happy to utilize her and become a character. As such, whilst there are a million and one different versions of Koakuma, it’s generally agreed upon that she’s Patchouli’s assistant.

For farming, Koakuma is reasonably strong, with a potent All targeting Last Word in Dreaming Necronomicon to get the job done, but can run into problems if enemies resist Fire and Moon. She’s better suited to Solo stages too than one might think for an All targeting Last Word, as Demoncraft gives her 3 levels of Yin DEF DOWN against a single starget, which helps her damage output tremendously.

In harder fights, Koakuma shines. Thanks to the 2-2-1 nature of her Last Word, alongside its remarkably high Slicing, being full Slash (to abuse the Story Card Mysterious Sword Master), and packing Yin DEF DOWN, she can do tremendous damage - on top of providing Yin & CRIT DEF DOWN to support her allies. This is further complemented by Pulverization: Pacifis Strike giving her 2 levels of Agility UP (with a 60% chance for 1 more) for 3 turns, alongside packing an above average 1/2/3 Solo targeting Fire Breaks for 0/1/2 Spirit Power. Sublimation: Magallanica Impact provides an additional 1/2/3 Solo targeting Fire Breaks for 0/1/2 Spirit Power, if more Fire Breaks are needed. Lastly, she’s got handy skills too: Language of Dragons gives her entire party 1 level of Agility UP with a 80% chance for one more for 2 turns (minor, but nice) alongside 1 layer of Blind to all enemies for 2 turns (which is also minor but can be abused by Blind Breakers and herself), and Demoncraft gives one target 3 levels of Yin DEF DOWN for 3 turns to take them out right away, alongside Quick for Koakuma to make sure she can provide further Yin DEF DOWN through her Last Word for her teammates.

Additionally for Breaks, Dreaming Necronomicon packs a extremely impressive 3 Fire and Moon All targeting Breaks for 3 Spirit Power. And unlike other Last Words, it doesn't sacrifice damage in the process, due to providing its own Def DOWN support.

Overall, Koakuma is, in spite of her name and appearance, a very potent friend, especially in Yin or CRIT teams, and will serve anyone well. Sure, she’s Patchouli’s servant on paper, but she’s got enough time to do a few chores for you! Even if she may whine about it. 

The Slicing scaling of Dreaming Necronomicon is 30%/35%/0%/40%/0%/60%. Note that the Yin DEF DOWN on it also scales with Boosts, becoming a 100% chance for 2 Levels of Yin DEF DOWN at 3 Boosts.

Story Card Recommendations

(Card recommendations last updated on May 15, 2023)

Spell Card

Koakuma simply needs Spirit Power, Yin ATK and Accuracy to function. Her Killers are lacking in both quality and quantity so we won't worry about CRIT ATK too much here. That said, let's focus on Spirit Power, and cards like The Witch of Scarlet Dreams, Youkai Mountain Anniversary or Mountain of Faith can help cover that with their increase of it by 2.00. Yin ATK boosters are worth noting too, such as Overwhelming Firepower, Rainbow Dragon Cave, or Redder Than Blood. Cards that can support her team or can be used as debuffing outlets include Mansion of Memories, Worlds in Hand, Glistening Summer Days, Flight Through Silence or Ability Cards? can really benefit the team's damage output one way or another, with the last one in that group also benefiting Koakuma since she might need that Accuracy herself.

If for some reason you want to use Koakuma's Spell Cards for damage, her first one can use cards like Choose an Animal Spirit, Stand-In Shrine Maiden and Beach Sanshoku Geidontei for the first Card, and The Secret God of the Sky works just fine for her second option.

Last Word

There are multiple different routes you can take with Koakuma. The Classic Mysterious Sword Master path provides her a 50% boost in Slash while adding that extra Accuracy for consistency. The Moon and Izayoi could be an option since technically the 50% Slash boost there works, but no Accuracy could hurt, and you might not find a situation where you would use that over Mysterious Sword Master.

An interesting path you could take include a mix of Fire, Slash, and Yin ATK boosting in the form of Redder Than Blood, which can definitely benefit Koakuma as a quick burst of power.

Finally, you could go insane with debuffing, should you have the cards to do so. Glistening Summer Days does a lot for Koakuma specifically. Being a Debuff Class Friend allows her to reap the benefits of the card's All-Targeting Yin Debuffing while also boosting her Fire bullets by 35%. Another unrestricted role option that can also do this job well is Flight Through Silence, since it can go insane with all its debuffing, notably Yin DEF and Evasion on all enemies. These 2 options might just have their niches in harder content against enemies without any Barriers to break, or can simply be used to set up for a Yin ally's nuke.

Character Skill Level Up Recommendations

Demoncraft benefits the most from levels, and should thus be maxed out first. After that, Language of Dragons provides a decent bonus, and should be maxed out (though it unfortunately never becomes a 100% chance for another level of Agility). Lastly, Devil of Literary Revival is very weak in the current LostWord meta, and can be saved for when you have no other targets or for when Koakuma gets a Fantasy Rebirth.

Character Strengths

+Strong All targeting Last Word that gets very powerful in longer fights
+Overall good Break potential
+Team support in the form of Yin & CRIT DEF DOWN

Character Weaknesses

-Not quite as strong as other top tier attackers
-Only provides DEF DOWN for Yin or CRIT attackers
