Onee Chan wa Koi Youkai

Finished

お姉ちゃんは恋妖怪

Yuuki Kuwahara decides to move into his father's old family home when he starts high school, hoping to live independently. He carries a faint, nostalgic hope of encountering a mysterious girl he met there once in his childhood.

To his surprise, the supposedly empty house is not vacant at all. He is greeted by an unexpected resident: a supernatural youkai girl who takes the form of an affectionate older sister. Thus begins their new life together under one roof.

As Yuuki navigates his new high school life, he must also adjust to cohabiting with this playful apparition. Their daily interactions blend the ordinary with the supernatural, sparking a unique and slightly risqué dynamic between the human boy and the youkai onee-san.
