"Thank you for the compliment, sir!" "Well, you're welcome, Aizen, let Niryuri have a taste of what life is worse than death!" "No, sir, you can't blame me. What I'm good at is biological genetic research, not time and space travel~~~" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
