Shimitsuki (しみつき)

Overview
Shimitsuki (しみつき) is the protagonist of If.

Appearance
Shimitsuki has shoulder-length light brown hair, with a pale-yellow hair tie that makes a mini side ponytail on the left side of her head. She wears a hot pink tank top with stains/blots of possibly yellow paint/ink on her shirt. She has grey shorts that are dark grey on her sprite, but have been depicted as light grey, even in official art. She wears salmon-red shoes on her sprite, but has also been drawn with dark grey shoes.

Personality
Shimitsuki can be assumed to be young, her "dreams" are rather whimsical and tend to involve circuits, wire or other themes related to technology, so it is possible she has a fascination with the inner workings of electronics.

Past
Not much is known about Shimitsuki, but based on the beginning of the game, it can be assumed that she has only recently shut herself in her room, or woke up in a locked room. There is no backstory or reason on why she has a portal behind her bookcase either.

Highlight at your own risk.

In the ED2 and ED3, after you selected the Name (なまえ) from the girl live in the Monochrome Villa, Shimitsuki's name in the menu will change to Izumi (いずみ, 泉 = spring fountain / common Japanese name), seems like it should be her real name in the past.
