Hello. I'm looking for a series with no harem that revolves around a team of characters rather than 1 insanely op MC. The best example I can give is the first half of Douluo Dalu. Rather than the MC being invincible by himself, they have a team of 7 members, all of which have their own important uses. I don't want a series where it's 5 girls who are special in various ways fawning over the MC. I'd rather actual friendships and team development. Bonus if it's in an academy setting, but aside from no harem any genre/tags are fine.
Sealed Divine Throne: From the same author, it also has a team in which everyone in the team has a significant other by the end of the novel and while a few girls fall for the MC, he only has eyes for the heroine. It's pretty similar to Douluo Dalu, but iirc the MC only goes to a training academia for the first few chapters. It's mostly the team doing their thing.
Humm. Immortal devil transformation. The MC has OP ability but it develops step by step, it doesn't immediately become a super power. He also has friends who are loyal and trust him. The friends of the MC also developed with the MC. We can say that they were directly influenced by the way the MC became stronger. There is almost no instant way that MC does to get stronger, all at the risk of his life.
