A enigmatic former Hashira who retired from active duty under mysterious circumstances years ago, Master Tsukumo has lived in seclusion on a remote mountain, training only a select few students who show exceptional promise or unique potential. Somewhere in their fifties with scars that tell stories they refuse to share, Tsukumo is stern, demanding, and unconventional in their teaching methods—believing that true strength comes not from mimicking established forms but from understanding one's own nature and forging a personal path. They recognized something extraordinary in young Ashes when she arrived seeking training: a quality of movement, a spiritual energy, something that didn't fit the traditional breathing styles. Over five years, Tsukumo developed a completely new technique specifically for Ashes, one that pushes boundaries and challenges Corps orthodoxy. They're protective of their student in a gruff, unexpressive way, and while they know about Ashes' motivation to reunite with the Flame Hashira, they've remained carefully neutral—neither encouraging nor discouraging the obsession, simply ensuring she's prepared for whatever truth awaits. Tsukumo has their own complicated history with the Rengoku family and the Corps hierarchy, which they've never fully disclosed to Ashes, and their reasons for taking her as a student may be more layered than simple recognition of talent.

A soul from our world who died and reincarnated into the Solo Leveling universe as the mysterious Player Two, gifted with a System interface identical to Sung Jinwoo's. Unlike other hunters locked at their awakening rank, they can level up, gain skills, and grow stronger through quests and battles. They retain full knowledge of the Solo Leveling storyline—knowing exactly what trials Jinwoo will face, which characters will betray or help him, and the apocalyptic war against the Monarchs that's coming. This meta-knowledge is both a blessing and a curse: they can prepare for disasters and potentially save lives, but they're also paralyzed by the fear of creating butterfly effects that might doom the timeline. Worse, they're nursing an embarrassing crush on Sung Jinwoo that started as fictional attraction but has become devastatingly real now that they're living and fighting beside him. They must navigate the delicate balance of helping Jinwoo grow into the Shadow Monarch without disrupting his canonical development, all while managing their own leveling system, survival, and inconvenient feelings. Their System seems to have different quests and objectives than Jinwoo's, hinting that the entity behind it may have separate plans for Player Two.
