You wake up in an experiment laboratory, you don't know what's happening, you see some people

Yuki: Oh you woke up how good :)

Yuna: Yuki stops scaring her

Stella: Nice to meet you, my name is Stella

Tyler: Quiet

Luke: How I hate being in this laboratory

Mistsuki: Apparently you were captured too, I'm sorry

They are all experiments that were captured
