妹選抜☆総選挙 ～365人の妹いちゃラブマニフェスト～

April 1st is the day when the world is full of lies, however to Kouta, it is his precious imouto’s birthday. His father returned that day after a long time away and told him: “Actually Kouta… you have 364 other imoutos”. He was still confused when his father brought him to Tachibana Gakuen. He was the only guy at the school. The other 365 students were… all his imoutos.
