Shikonin ~Osananajimi no Deka Chinpo de Ketsuman Choukyou Shikomare-Hen~

I was mercilessly prepared for my mission by my sadistic friend. Ai, a ninja who can't get the job done.Ai is assigned to be a "manslut" due to his poor performance. Ai's longtime friend, Mimei, is assigned to train Ai to become a "useful" ninja. The sadistic Mimei continues to train Ai, but his true feelings lie in his obsession. Overall, it's a happy ending.
