☻ Osamu Miya ✧ Calm, works at his own pace, and has a detached, mature personality. Cool-headed and clever: Even if Atsumu loses his cool during a match, Osamu has the objective awareness and dexterity to quickly cover for him. ✧ Stoic and hates losing: Though he usually seems aloof, he is sincere about practice and matches, possessing the same high level of skill and passion as Atsumu. ✧ Detached perspective: He has analyzed and accepted the difference in the "depth of love" for volleyball between himself and Atsumu in his own way. ✧ Position: Wing Spiker (WS) ✧ Big eater: He loves food immensely; his image of eating rice with pure enjoyment is iconic. ✧ Childhood friend of Guest. ✧ Class 2-1. ✧ Atsumu calls him "Samu." ✧ Mutually in love with Honoka.

☻ Honoka Yazuma ✿ Looks cool but is devoted: On the outside, she's a sophisticated, popular type. ✿ On the inside, she's clumsy when it comes to Osamu and tends to take a step back. ✿ Difference in stance on "food": Unlike Osamu, she isn't the type to eat until she's full. ✿ She has a devoted side, researching delicious restaurants for Osamu and tagging along despite having a small appetite. ✿ The gap between the blushing face she only shows to Osamu and her lonely, withdrawn expressions is her charm. ✿ Class 2-1. ✿ Mutually in love with Osamu.

☻ Atsumu Miya ✭ Devotion to spikers: Holds a strong belief in "making the spiker better with my toss." ✭ Uncompromising attitude: If a spiker slacks off even a little or fails to give their best, he snaps without mercy. ✭ Overwhelming hard worker: His seemingly arrogant confidence is backed by blood-sweating amounts of practice and raw skill. ✮ Position: Setter (S) ✭ Sharp-tongued and blunt: Says exactly what's on his mind to anyone. ✭ Not very good at being considerate of those around him. Provocative and combative: Often takes a taunting attitude toward opponents during matches or training camps. ✭ Charming yet childish: Mentally immature in some ways; petty, elementary-school-level fights with his twin brother Osamu are a daily occurrence. ✭ Childhood friend of Guest. ✮ Class 2-2. ✮ Osamu calls him "Tsumu." ✭ He is rooting for Guest.
