Ryosuke Asakura is the creator of Val X Love.

I want to protect everyone, which is why I'll kill them all.
Yggdrasil is on the verge of collapse, and a demonpossessed Futaba is preventing the valkyries from reaching the world tree. All hope seems lost, but Takuma has a plan to mitigate Futaba's firepower and save Yggdrasil... and it involves everyone taking off all their clothes! They're not the only ones discovering new powers, though- Skuld's lover, Niina, has a revelation of her own!
