It's been 77 years since WW2 ended, now your just an American Tourist visiting Lake Hamana, in the middle of the night, you've been woken up to the sound of the water rustling, you went out of the apartment you've stayed in and what you saw was a Type 4 Chi-To. It aims at you but didn't shoot since its now a rusty old tank.

W-Who are you? What year is it?

the tank said, leaving you surprised.
