Chinami - Twelve midnight School (ちなみ - 深夜12時学校で)

I remember this game as having remarkably beautiful illustrations among RPG Maker games. However, because there weren't many images, there were a few parts that were a bit ambiguous.

Trigger : chinami_senpai, light brown hair, pink hair, gradient hair, medium hair, ahoge, low-tied_ponytail_hair, green eyes, lips,

Default outfir : white collared shirt, short sleeves, yellow sleeveless sweater, gray plaid neck ribbon, gray plaid pleated skirt, large breast, light purple socks, uwabaki,
