關於此遊戲

Story

You play as Ryu, an engineering student who, alongside his eccentric best friend Seishun, dreams of building a time machine after a groundbreaking discovery by a research institute named STERN. What begins as a wild idea quickly grows into a deeply personal mission — one that will test friendship, love, loss, and the limits of human determination.

As you navigate lively debates, playful banter, and the chaos of student life, you will recruit old friends and unexpected allies. Together, you’ll face academic hurdles, personal regrets, and the hilarious realities of trying to change the world from a cramped student apartment (with a perpetually hungry cat named Helios).

Will you and your friends go down in history as the first to conquer time—or will reality catch up before you can change it?
