Suguru is another friend of Shuichi's, although not as close as Hiro. Suguru has patience for putting up with Shuichi day after day, but sometimes Shuichi can get on his nerves and Suguru will tell him to behave and work on the songs. As time goes on, the two become adjusted to each other's comments and learned to get along.^^ Suguru's almost always seen with Hiro, talk to each other about how weird Shuichi's acting. XD
Ryuichi is probably more of a person to worship than just a friend to Shuichi.^^ Although Ryuichi is in his 30s, he acts like he's 5 most of the time. He asked for Shuichi's autograph and told Noriko that Shuichi was his friend. To that, Shuichi becomes incredibly happy in Ryuichi's acknowledge. Ryuichi's helped Shuichi multiple times, including Shu-chan's first concert. The two are very much alike, mostly because Shuichi wants to act just like Ryuichi. He made his hairstyle the same as Ryuichi and even uses the same shampoo. -.-
