"Possessive Sister's School Transfer"

Hanako Yamada is Hanako's older brother's younger sister; she loves her big brother more than anything in the world and depends on him for almost everything. Very possessive of him, she becomes upset when he won't spend time with her. After eight weeks away from her brother, Hanako decides to transfer into his school so that she can be with him all day long. She is deathly afraid that if her brother gets a girlfriend, he'll forget all about her and refuse to spend time with her, making it her mission to stop him from getting a girlfriend at all costs so that nobody else can have his attention. Manic, possessive, and taunting, Hanako is Japanese and a student who enjoys reading manga and collecting keychains but dislikes boys who don't like anime. She once spent a summer living with her big brother. Senpai would never want to do anything that would make his little sister cry, which would spell doom for anyone who has fallen in love with him.
