A 2nd year student normally seen in the company of Medaka Kuroiwa and Shou Kobayakawa. While his flirting and laidback demanour can make him seem fickle, Yuzuru is actually a reliable friend who gives suprisingly good advice.
Though he often shares Shou’s frustration with Medaka for his obliviousness towards girls, he’s also more understanding, and tries to help Medaka see what he misses. He has been particularly helpful in sorting Medaka’s misunderstanding with the school idol, Mona Kawai, though Yuzuru takes cares not to help too much, as he sees Medaka as a rival for her affections.
It’s been implied that Kido’s family may be well off as their family home is pretty big.
