In the beginning of the series, Ikuyoshi worked as a host at the same shop as Haru. He dropped out of high school and became a host mainly because he has always admired and looked up to Haru.
When Haru told Iku that Ren was spending most of his time at the library, and that he was into Japanese and Chinese classics, Iku replied that he didn't think he and Ren could be friends.
After Haru decided to open up a restaurant, Iku excitedly quit the club as well. His family consists of nothing but farmers and thus they supply Haru's restaurant, "White Fang", with all their fresh vegetables.
When Iku first started helping out with the opening of the shop, he was shocked to see Haru and Ren kissing. When he questioned Haru, he was only given the very vague answer of "Isn't this normal?" Eventually, he comes to accept Haru and Ren's daily displays of affection. He also gets along with Ren, giving him the affectionate nickname of "Ren-Ren".
Ikuyoshi comes from a large family of farmers, with his older brother helping out with the family farm and his two older sisters both marrying farmers. His family farm is located in Chiba and is one of the suppliers for "White Fang".
