Strategy
This is the most powerful enemy in the game, so it goes without saying that caution is vital. At the start of the battle, your own attacks will do little damage. However, over the course of the first few turns, Rotkäppchen will give you extremely powerful and permanent stat buffs, give you the powerful skill Lust Burst, and eventually reduce Lust Reaper's defensive stats to 0.

For the first few turns, use Embrace! twice to debuff Lust Reaper and then Defend to minimise the damage you take. Once Rotkäppchen debuffs her, you can begin attacking, with a focus on Pussy element skills. However, be warned that when she reaches half Vigor and strips, she will inflict Ecstasy and Fascination on you with 100% accuracy. To counter this, make sure your Vigor is full (or nearly so) and Lust Reaper is debuffed before you reduce her Vigor to this level. This will allow you to survive her attacks for the few turns that you're helpless. Once you regain control, finish her off as soon as possible. If you take too long, you'll only grow weaker due to repeated level drains, making the battle more difficult. Since this is the last and most difficult fight in the game, don't bother saving your items and use them as freely as needed.

After getting the True End, it is possible to rematch the Lust Reaper. At the end of Grimmspace is a cloaked NPC. Speaking to it will prompt you with "...You want to fight [Her] once again...?" Saying "Yes" will trigger a fight against the Lust Reaper. While she is no longer nigh-invulnerable at the start of battle, you do not get any buffs from Rotkappchen.

H-scenes
Lust Reaper has the standard set of H-scenes: one for losing to her the first time, one for subsequent losses, one for surrendering to her, and a Unique END that can only be viewed in the Succubus House. These have her give Magrut a titjob, during which the player is presented with four choices that are all the same ("I want to be your slave" in the first two scenes, "I submit myself to you..." in the surrender scene and "I Submit!!!" in the Unique END). The second and fourth scenes also have Lust Reaper rape Magrut in the cowgirl position.
