Synopsis

Makoto Kaoru got reincarnated and received a guild building as a cheat and with this cheat, he needed to protect his world and the other world in the multiverse.-----The MC will not be insanely overpowered but still on a tolerated level and the main enemies will not be too weak or too strong, I will try to make it balance as much as possible.Will there be a harem? I love harem but I don't know whether I will add it or not but expect it a harem will exist in the futureNote: I only own the MC, the other characters belong to their respected authors/creatorsthe cover is not mine, it's made by Parum so feel free to contact me if you want me to change it
