I went into this knowing it was an isekai but hoping it would be interesting due to the premise. The MC is reborn as a child with all the experiences and memories of being a jaded and skilled assassin. Except, the plot never goes anywhere with this. If they didn't tell you he had lived the full life of a man in the previous life, you would never know. Boring characters, and an even more boring MC. The side characters are all young girls (go figure), and only serve to be his servants who are sexualized at every turn. Complete waste of time to watch. Only good episodes were the first one where the MC was still in his previous life and actually had personality, and the other was the episode where he wasn't really in it at all. Awful show.
