Isekai kara Tensei shita Ore wa Yami no Chikara de Yuusha Party ni Fukushuu suru

One day, the shock of falling down the stairs brought back memories of my past life. I remembered two things.First, the bitter memory of being one of the Four Heavenly Kings serving the Demon Army, defeated by the Hero’s party.Second, how to use dark magic to control the human mind. I immediately put this dark magic to use and successfully subdued Hina Kato, the reincarnation of the female warrior, and Hibiki Kasamizawa, the reincarnation of the mage. My next target was Saki Hanamura, the reincarnation of the priest.Learning that she had to attend a remedial swimming class, I decided to use my dark magic to summon tentacles and humiliate her right inside the pool.
