History
When young, Reiji was training to be a member of the secret organization Shinra like his father Shougo Arisu. Ten years ago, in Shibuya, Reiji tried to protect his father from Saya, and he got hit in the head and passed out. When he awoke, the battle was over and his father perished, believing that Saya killed him. The scar in his head pulsates when Saya is close.

Namco X Capcom
Reiji is now a member of Shinra, which investigates disturbances in space and time called "fluxes". He is a no-nonsense, hot-blooded fighter who wields an array of pistols, shotguns, and swords.

Endless Frontier
After the events of Namco X Capcom, Reiji and his partner Xiaomu were still chasing Saya. After Saya had escaped to the Endless Frontier, he and Xiaomu decided to follow using the flux.

After arriving in Mirabilis castle, they had a run in with Haken and co. After Haken defeated the two, they both explained the events leading up to thier battle and what both groups were after.

Reiji and Xiaomu then teamed up with Haken not only to find a way back home but to bring Saya back home with them.
