Although his face is never shown, he is seen to be wearing glasses and has somewhat curly light brown hair. Setsuna Kiyoura and other characters describe him as a "hot guy".
Like most other boys, Ikeda envies Makoto's popularity with girls. This lends into their exchanges as they prepare for Haramihama Shrine's summer festival, which are tense if not outright hostile. This envy is later alluded to by Otome, who tells Setsuna that along with Ii, Ikeda was one of those who fell out with Makoto.
