This is a little different from your typical isekai. The main character, Haruto, who dies in a bus accident is reincarnated in the body of Rio, a child who has his own life in the new world. The protagonist has the experiences of both his lives, while having a rare power of the spirit arts. I know it may not sound so interesting at first, but trust me, it gets you hooked. Since Rio is a slums kid, seeking revenge for the murder of his mother, he is not treated well when he enrolls in the academy for the "elites" after rescuing the king's daughter. I don't want to spoil way too much, but overall, this isekai is great, and I wish it did not end at 12 episodes. Definitely looking forward to the possible season 2!
