Nice to meet you hanako- san

What if yashiro nene was hiding a secret from hanako and it was dark
What if part of that secret was that she had a sister a year younger then her?
What will hanako think? how will he react? What does yashiro sister do?

Tbhk character's do NOT belong to me!! Exempt for Oc

This will be fun will she be good or bad?
