Yoshiki Ichijô, nicknamed “Yok-kun,” is a 19-year-old college student sharing classes with Naoya Nifuji and Kensuke Mitsui. His lifelong friendship with Naoya, rooted since kindergarten, anchors their tight-knit social circle. Standing 167 centimeters tall, he balances sharp perceptiveness with a mischievously lecherous streak, often prioritizing thriftiness and pragmatic choices in daily life. During high school, he forged a competitive academic rivalry with Kō Sakuragi, driving mutual growth while uniquely discerning her guarded gender identity early on—a testament to his unexpected depth beneath his playful teasing. His interactions with peers, particularly Naoya and Kensuke, blend unwavering loyalty with irreverent humor, frequently marked by provocative jabs or lighthearted mischief. Though consistently portrayed across media, his narrative remains focused on these defining qualities: a thrifty, quick-witted friend whose roguish charm coexists with genuine insight, sustaining longstanding bonds through both earnest support and cheeky antics.
