Sailor Moon: Usagi Tsukino

The leader of the Sailor Guardians and the main protagonist of the series. Sailor Moon is a reluctant leader who is willing to push herself to the limit to help her friends. Sailor Moon may be a bit dramatic, lethargic, but they are hopeful optimists who believe in the natural goodness of all living things.

Her civilian identity is Usagi Tsukino, she is clumsy and childish, especially at the beginning of the series. As the show progresses she is forced to deal with difficult situations, she becomes more bold and capable. She becomes more confident in herself and an inspiring leader as well. She cares deeply about her friends and family and this is why she ends up being a bit too nosy for her own good. She is generous to a fault, and she even gives villains the benefit of the doubt so they could possibly redeem themselves. 

I think the Shikkie character/characters that resemble Sailor Moon: Usagi Tsukino the most are Park Hyungsik himself, Minhyuk, Dalbong and maybe Changsoo.
