Yutaka Itazu, nicknamed “Panties” or “Pantsu,” is a reclusive NEET and prodigious hacker whose intelligence and technical prowess contrast sharply with his isolated lifestyle. The moniker stems from the kanji in his surname and a humiliating incident where his sole pair of pants was swept away by wind while drying, trapping him indoors without replacements. This event catalyzed his retreat from society, prompting him to abandon university studies despite prior academic dedication.

He now resides in seclusion within a cramped apartment, barring visitors and habitually驱逐 intruders with sharp commands. Renowned for his hacking expertise, he contributed technical guidance to the Eden program, a photo-based search system designed to identify individuals. The lost pants incident remains a defining symbol of his rejection of societal expectations, anchoring his choice to sever ties with the outside world and embrace solitude.
