Nozomi Mori, a second-year Eiryou High School student and student council vice president, serves as the primary straight-man counterbalance to president Chihiro Uomi’s comedic chaos. Initially referenced only by surname, her full name emerges in Chapter 415, though her first appearance occurs earlier in Chapter 300 during a school exchange where she aids Shino Amakusa, noting Shino’s quirks rival Uomi’s unpredictability. Tasked with upholding order, she routinely counters Uomi’s mischief, including defusing suggestive comments about overnight stays at a male acquaintance’s home that spark peer rumors.

Her disciplined nature fosters a professional kinship with Ousai Academy’s vice president Takatoshi Tsuda, both serving as composed mediators. Their collaborative dynamic occasionally fuels misunderstandings—like when Mori hands Takatoshi a key on Uomi’s behalf, igniting romantic gossip. Tensions escalate when Takatoshi accidentally intrudes on her changing clothes at his residence; their pact to conceal the incident unravels as whispered discussions amplify speculation.

Mori gradually cultivates confidence beyond her duties, confronting insecurities about her swimming skills through persistent practice at Ousai’s pool with council members’ support. While resolved to demonstrate her progress, classmates redirect attention to her physical maturation. She engages in joint Eiryou-Ousai events, from cleaning projects to trips, deploying precise comedic timing as tsukkomi during absurd situations. A hot spring outing highlights her fiercer side when she sternly halts Shino and Uomi’s mudplay, earning Takatoshi’s awed acknowledgment of her intensity.

Though Uomi affectionately calls her “my right hand,” relying on her organizational prowess, Mori critiques Uomi’s wilder impulses—like covert plans to dress Takatoshi in matching outfits. Her pragmatic approach anchors the council, offsetting peers’ eccentricities through levelheadedness and dry wit, solidifying her role as the group’s steadying foundation.
