Yutaka Itazu, nicknamed "Pantsu" (meaning "Panties" or "Underpants"), earned this moniker after his sole pair of pants disappeared while drying outside, leaving him unable to replace them long-term. This incident significantly fueled his descent into a reclusive NEET (Not in Education, Employment, or Training) lifestyle, prompting his withdrawal from university despite prior diligence. He retreated into his small apartment, refusing to leave or admit visitors, often responding unfriendlily to those at his door. Before withdrawing, he was a highly skilled hacker, once feared as a "prodigy" or "genius" due to exceptional technical abilities. This expertise led to his initial involvement with the Eden group, providing technical advice for their image recognition software. His circumstances shifted upon encountering Akira Takizawa and Eden. During the missile crisis, he played a critical role by analyzing Takizawa's and the deceased Seleção Yūsei Kondō's special Noblesse Phones. Using his hacking skills, he accessed the Seleção request logs stored by Juiz, the game's concierge AI, uncovering crucial information including other Seleção identities and the impending launch of sixty additional missiles by Seleção members Daiju Mononobe and Ryō Yūki. After transmitting the entire Seleção database to Eden for safekeeping, Mononobe targeted him, striking him with a vehicle in an attempt to silence him. He survived the attack and recovered in a hospital. Following these events, he formally joined Eden of the East, becoming an integrated team member. His technical skills remained vital to the group's operations, especially after they established a successful business using their image recognition technology. Six months after the missile crisis, during the events of *The King of Eden*, he is documented as an official member actively working within the Eden group's headquarters. This integration marked a significant shift from his isolated NEET existence to a socially connected role where he collaboratively utilized his hacking talents. He has brown hair and grey eyes.
