New Life in a New World (Konosuba x OC Reader)

Joichi Shiobana was just a regular student, attending a regular school. You could say it's quite a regular life. One day, he met quite an unfortunate end to it. He is given the choice of being reborn back in Earth as a baby, but with no memories of his past life, going to heaven, or being reincarnated into a fantasy world being terrorized by the fearsome Devil King.
