^^^ those are either not romance or has a rather innocent heroine (by my definition). But ofc, the characters and plot still has some great depth since it's still one of my favorites. So do check them if you have the time (:
Can someone recommend a shoju with a tomboy female lead and mature art style. The girl should not be all innocent and cute. She doesn't necessarily have to be a tomboy just not the innocent and cute type.
I'm kind of thinking about something along the lines of NANA with the rock Nana.
Happy ending is required :3
