Tomoegata Naginata embodies an amalgamation of all ceremonial Tomoegata-type polearms, distinguished by a wide blade and pronounced tip curve. This collective origin denies him individual historical anecdotes, inscriptions, or a singular forging legacy, leaving him without a traditional sword name or documented past prior to his summoning by the Saniwa. He perceives his existence as beginning at that manifestation within the Honmaru.

Standing 193 centimeters tall, his stature is potentially amplified by footwear, and his appearance features distinctive elements like a monocle. In battle, his naginata design enables sweeping horizontal strikes against multiple foes. Achieving Kiwame status markedly enhances his combat prowess, elevating leadership, impulse, impact, and scouting capabilities while granting an additional troop slot.

His demeanor radiates divine detachment from human traits, coupled with fierce, singular devotion to the Saniwa. He prioritizes the master's comfort and safety above all, maintaining constant attendance with meticulous care. This loyalty borders on overprotectiveness, sparking possessiveness and a rivalry with the equally dedicated Heshikiri Hasebe as they vie for the Saniwa’s favor. Beyond service, he lacks personal interests, yet keenly observes interpersonal tensions and mediates conflicts among comrades, such as reconciling disputes within his assigned Third Team. A competitive streak emerges in matters concerning his master, and his overprotectiveness fuels comedic clashes over Saniwa access. Though lacking direct interactions with his combat-oriented counterpart Shizukagata Naginata, their ceremonial-versus-martial contrast holds thematic potential.

He manifests during specific Honmaru events and participates in campaigns like Village of Treasures or Regiment Battles. Availability includes limited-time smithing events and regular Era 4 campaign nodes.
