Reiji is a mysterious boy who Sei Iori encounters in town. He is overbearing, selfish, quick to anger and lacking in manners, because he is from a different planet. Reiji has shown a naivety with Earth customs, such as comparing Rinko Iori and China Kousaka's breast sizes out loud, ending with him getting slapped, and taking food he thought was discarded from a shop, solely because it's placed outside.

However, Reiji has shown a noble side, helping others in their times of need. Despite him being inconsiderate, he is not totally devoid of social sense, shown when he chastises Mao for the failed date due to Mao being too straightforward, and that Mao should not have attempted to kiss Misaki right from the start.

Reiji initially has no idea about anything regarding Gunpla or Gunpla Battle, and was only into it for returning Sei's favor and that it seemed fun to defeat other Gunpla. Over the course of the time he spends on Earth, he gets more and more interested in Gunpla due to Sei's influence and other players around, eventually culminating in him building his own Gunpla - a GPB-X80 Beginning Gundam.
