Description
Osamu Osanai is a short-statured student sporting black hair in a bowl cut, typically clad in his school uniform: a white button-up shirt with a chest pocket and matching pants. His large square glasses often reflect light, obscuring his eyes. During a gender-swapped dream sequence, his appearance shifts to a bob haircut and female uniform while retaining core features.
He openly expresses a distinct preference for small-breasted girls on multiple occasions. As a dedicated manga club member, he constantly carries a sketchbook, sketching subjects of interest during daily life and supernatural investigations. He emphasizes drawing as integral to his identity, sketching wherever he is.
Within Kazuya Kagami's friend group, he frequently appears alongside Shirou Shiramine and Chisato Chikaishi. Early interactions involve him discussing Kazuya's accidental groping of Chisato and later witnessing Kokuyou's school disruption, where he sketches the chaos. He loans Shirou 500,000 yen for restaurant debts, creating financial tensions. His supernatural involvement begins when assisting investigations into Eiko Nago's ghost, gathering testimonies from classmates and faculty.
His strategic thinking surfaces during Hiroshi Ohkado's amasogi incident, where he explains "Pure Heart" gameplay mechanics to Kazuya and devises a rescue plan for Chisato. His advice includes the critical "Plunder Combo" tactic. Later, he joins the Counseling Office Club to address amasogi incidents, identifying a help request tied to Mitsuri Mizushima's case and contacting Nanako for information.
During the Reversal Arc, he demonstrates foresight by writing a dream world reminder in his sketchbook before entering teacher Isuzu Iriha's subconscious. The message alerts the group to their reality upon opening it in the dream, enabling them to confront the amasogi threat. Inside, he briefly participates in gender-swapped school routines before helping locate the hidden amasogi. He deduces the true identity of a girl impersonating Isuzu, advancing the group's mission.
