Honestly I love. The MC knows Momonga so it will be exciting to see those two meet up. Also the MC should be honest but not naive and innocent, he's a seraphim not a child, he should kill when he needs to nothing more nothing less. Those are just my thoughts. Author are you gonna come back to this book because I would love to this continue, it's so hard to find good overlord fanfics, plus ones that have an Angel as a MC is rare for novels as a whole from my searching.
