Kodera has brown hair slicked back, with short messy upward hair on his fringe. He also wears glasses.
Like the rest of his unit when in Trigger mode, he gets a flak jacket, headset, padded gloves, and zipped-up Wellington boots. Being a Sniper, he usually equips Bagworm over his clothes.
Kodera is a well-mannered, somewhat timid person, but has learned to put his foot down when the need arises. He has a lot of respect for his teammates, principally Narasaka, whom he considers his higher-up. Due to his house being destroyed by Neighbors, he dislikes them. But he doesn't seem to be as serious about it as Miwa or Narasaka.
Shiori Usami: Kodera appears to have a crush on Usami, as exhibited by his behavior in Chapter 92 when Usami compliments him on his commentary. He also is envious when Kikuchihara is put into a headlock by her.
