ACE OF BEASTS has a lot of content warning stuff and deals with some sensitive topics - although it's focused on healing, there is some depiction of upsetting stuff in a non-romanticized context.
For lighter content of mine, I'd suggest MEN+MONSTERS (funny but some introspective stuff in later chapters), Knights Beyond the Stars (total space clownery), and maybe Sanctuary Guardians (it's a maybe because there's some monster / magic versus human fantasy bigotry depicted in the backstory of some of the characters, but otherwise it ranges from lighthearted to lightly angsty).
Overall, as a reminder, ACE OF BEASTS is a survivor story. Thanks for reading {:^>c
