"There are lots of ties between him and me."

"What's going on, Grandpa?"

"I'll tell you in detail next time. In short, now you have to be extra
careful, and if possible, do not approach that man."

"Even if you tell me not to approach him, I don't know what he
looks like."

Kirigiri said a little troubled.

"His appearance has no reference value. What he is good at is
camouflage and disguise. He is a Variationist who won't let
anyone see his true face."

"Then how are we to be careful."

"I'll tell you his name. If you hear that name, run away no matter
what."

"This’s... too excessive." Kirigiri shrugged. " And the name of that
man is?"

"Shinsen Mikado... the former Triple-Zero rank detective."
