Niko Ōno, a sharp-eyed member of her school’s newspaper club, sports black hair swept into a carelessly tied ponytail and vivid green eyes that mirror the color of her non-regulation sweater—a deliberate break from standard uniform attire. Her relentless curiosity and tenacity drive her to chase leads for articles with single-minded intensity, brushing off warnings from peers who question her methods.

Tasked with aiding Konoha Suetsugi in investigating Kobeni Yonomori and her family, Niko dives into the assignment with fervor. But when Konoha withdraws upon realizing the distress their probing causes Kobeni—a girl who shuns the spotlight—Niko refuses to relent. Her sights remain fixed on clinching the editor-in-chief role by unearthing impactful stories, undeterred by setbacks or shifting alliances.

Interactions with Konoha and her newspaper club duties define her known engagements, with no extended background or external ventures documented beyond these pursuits.
