Studio Kingyoiro

Masaki, an average college student, is walking through the park when he crosses eyes with Abe, an older mechanic sitting on a bench. Upon seeing him, Masaki says to himself "Uho, hot guy!" while Abe promptly unzips his jumpsuit, reveals his "unit" out in the open and asks, "Shall we do it?". They then proceed to the washroom and have sex.

Two people separated by time and space must unravel their tangled history before the world comes to an end.
