Youmu Konpaku (Boss)
This page explains the strategies employed against Youmu on her boss fight. This includes party composition, which spells to use offensively and defensively, and how the battle should flow, which attacks to watch out for, etc. Since strategies vary greatly from route to route, explanations will be separated accordingly.
Quick Summary
Youmu is the first real boss of the game, and she can be quite hard if you don’t prepare properly first. In the speedrun’s case, that means losing to her 11/12 times to get Kasen. Since Youmu is weak to MYS, DRK and TRR, Kasen and Marisa can make short work of Youmu’s HP bar, killing her before she even gets a chance to use her nuke.

Strategies
Ame-no-Murakumo (NG)
Since we grind Kasen for this fight, she completely trivializes this by spamming Higekiri’s Cursed Arm. Marisa helps a lot by spamming Magic Missile. If done correctly, she will either die before getting to Concentrate, or soon after, before she can unleash God’s Slash of Karma Wind. The party composition is as follows, with the ideal actions to win:
Front: Momiji / Kasen / Keine / Reimu
Back: Kourin / Marisa
- Momiji attacks to delay her turn
- Kasen spams Higekiri’s Cursed Arm for massive DRK damage and TRR
- Keine spams Three Sacred Treasures - Sword
- Reimu uses Great Hakurei Barrier once
- Momiji swaps Reimu for Marisa then spams Rabies Bite
- Marisa spams Magic Missile
This should kill Youmu before she even has a chance to attack after Slash Clearing the Six Senses. Speaking of, this attack does not OHKO Marisa, even with no DEF buff, so it is safe to have her out before it is used. It is possible, but very unlikely, that Youmu targets slot 4 with her attacks when the battle starts or right after you switch Reimu with Marisa. Reimu might survive the hit, but Marisa will die to a direct hit, so you’ll have to play around her death. If she does die, do this:
- Swap Kourin where Marisa was
- Kourin spams Battle Command on Kasen
- Kasen concentrates when low on MP to keep spamming
- Try to kill Youmu before God’s Slash of Karma Wind kicks in
- Reimu can swap in to heal and rebuff if needed
