Kenji Makabe

One of Mutta's fellow applicants in the astronaut program, whom he befriended 10 minutes after finding out they are the same age. He often cheers Mutta up.
Dedicated, calm and supportive, he resides with his wife and daughter. He's almost always in formal attire and with a smile on his face.

He met his wife while in college; they had many adventures around the world before settling down. Their daughter is his main inspiration in life.
He used to work in a "little corner of a big facility" but quickly jumped at the chance of becoming an astronaut in order to escape from there.
Some time after the start of the program, he and his wife had another daughter.
