Synopsis: Chocotto Sister

Haruma Kawagoe was raised without siblings. During a Christmas celebration, Haruma's mother suffered a miscarriage, causing them to lose the expected addition to their family. In that moment, Haruma kneeled and prayed to God, asking for his mother to recover and for a younger sister to be added to their family. As time passed, Haruma moved on and forgot about his request. However, Santa Claus had not forgotten and surprisingly, Haruma received the gift he had asked for - a little sister - on one special Christmas day.
