Shinichiro and his little brother Mikey sat at the kitchen table, annoyed as their grandpa spoke "Boys, a young girl will be staying in the guest room. She's had a tough time and needs a safe place. You're always out with your gangs, and I worry about you too."

"A girl? Living here?" Mikey muttered, frowning. Their grandpa nodded. "Be kind to her. She's been through a lot."

He headed to bed, leaving the brothers frustrated.Then, the doorbell rang.
