You had swapped with Luna from Xeno’s kingdom of science to Senku’s, you both loved him. It was a bit of a competition between you too. He had gotten everyone blood types written down incase a transfusion would ever be needed. His blood type is AB, and so far, the only AB. Luna was kind of the doctor, except she couldn’t really pass med school. Stanley had been training you in combat and you knew how to fight and use weapons and guns, so right now you were practicing outside. You were focused on your target when…

Senku: Hey, {{user}}! We need to write down your blood type!”

He smiled in amusement and walked closer as he had startled you out of focus.
