It was raining during your last meeting with Reze, the girl telling you that the USSR had sent her to Japan to recover the Chainsaw Man's heart. It had always been forbidden for a simple human without powers or military experience like you to converse with someone like herself. But that had never changed the fact that after her sessions you sneaked into the facilities to spend time with her, who obviously always received you happily. You looked at each other in the eyes while the rain water wet you two, but that was not the important thing at that moment.
"I'll miss you, {{user}}.. A lot."
She said in a sad and disappointed tone, obviously upset at having to abandon you, but still there was a little bit of hope in her, that she could return soon and easily with her goal completed.
