The protagonist. Instead of going to college, the 19-year old helps his grandfather at his robotics workshop. Has a sunny disposition, but also a sharp tongue. He’s careful to calmly think things through. Because of his tendency to overthink things, he’s slow in making decisions, but once he has his mind set on something, he’s quick to get moving. He’s loved tinkering with machines since he was young. He becomes physically ill when he touches machines, though, so having to deal with them for long stretches puts him in a dilemma. Despite this, he continues to help out at the workshop, tinkering with his beloved machines. Keiji’s parents died before their time, so he feels indebted to Shino, who has looked after him since they were kids. Shortly after taking Kumiko under his wing and starting work as a full-fledged mechanic, an unknown organism from space becomes attached to him.

I really am at my calmest when I’m working with machines... ...Ugh...!

The game's protagonist. Instead of going to college, the 19-year-old has ended up helping out his grandfather at his mech workshop. He has a sunny disposition, but can be sharp-tongued. He's always careful to think things through as calmly and logically as possible. Keiji's life has gotten a lot busier since R-ne arrived, but he's pretty content with things as they are now. His parents died before their time, so he feels indebted to Shino, who's looked after him since they were kids. After leaving R-ne largely in Shino's care, he's left wondering whether she might be overstraining herself. Whenever he looks at R-ne, he's reminded of a girl he met long ago. Why can't he recall anything about her, though, despite being so curious about her true identity...?

I promised to return R-ne to her home planet.

R-ne's presence appears to be triggering huge changes in his relationships with the two women, though...

R-ne, let's get you home. Even if it means we'll have to say farewell.
