Sayu/Lust Grimm

Sayu is a boss in Lust Grimm. She is unique in that her boss fight is repeatable even before the player completes the Normal End. After being defeated, she remains in the same location and can be refought simply by talking to her.

Profile
''An Elf from another world who, somehow, found herself being transported to this world... Despite being transformed into a Succubus, she doesn't let it affect her mood. Instead she spends her days having fun and satisfying her incredibly large appetite.''

Strategy
Sayu can do a lot of damage, having an increased rate of inflicting OverLust hits. Consider healing more frequently to keep your Vigor above a higher margin than you normally would, in case you get unlucky and Sayu gets several OverLust hits in a row. She can also drain levels, so try and finish the battle as soon as possible to minimise this. Aside from these two factors, Sayu isn't that difficult, lacking a hold or any status effects besides an Agility debuff, so as long as your level and stats are sufficient you should have no trouble with her.

Trivia

 * Losing to Sayu raises Dependence by 8 points, more than usual.
