The Healer Ruins Princess Flare!

Kaifuku Jutsushi wa, Flare-oujo wo Kowasu! (回復術士は、フレア王女を壊す！)

Pretending to be afraid of absorbing painful memories, Keyaru swears never to heal again and pretends to allow Flare to imprison and get him addict to drugs, even allowing himself to be raped to further fool her. Flare begins forcing Keyaru to heal injured heroes, but Keyaru secretly steals magical abilities from them. Keyaru uses his stolen abilities to escape and disguise himself as Leonard, Flare's Imperial Commander, and, once alone with Flare, heals away her ability to use magic, rendering her defenseless. After repeatedly breaking then healing her fingers, Keyaru rapes Flare before he heals her in order to alter her appearance and memories. After healing a dead bodyguard's face to look like Flare, Keyaru frames Leonard before he escapes with the real Flare. Keyaru decides to target his other abusers, Bullet and Blade, before seeking out the Demon Lord he previously defeated to find out what she had been trying to protect when she died. With Flare now an amnesiac, Keyaru renames her Freia, convinces her she is his servant and lover while he changes his face and takes the hero name Keyarga the Healer, leaving his weak name Keyaru behind.
