Raichi is a big idol fan, so much to the point that Aoi has taken him under her wing in idol fandom. His relationship with Ichigo is that of a typical brother-sister acquaintance-type; they have their differences, but he still looks up to her in the sense that she is his older sister. This is commonly shown throughout the series, one of the most prominent being when he tried to keep her from seeing the photos of Mizuki he took and when Ichigo answered his question on the radio.
At first Raichi didn't have much confidence in Ichigo becoming an idol, but as time went on, he gradually began to see her talent and becomes impressed by her role as an idol.
Raichi has rust-colored hair and eyes, and is usually depicted in a teal-blue and yellow outfit.
