Gaioumon(Itto Mode)

The form of a Gaioumon defeated in battle that acquired new strength after unimaginable training. The oni data sleeping within its Digicore has awakened, and its fighting style has changed to Ittō-ryū. Having mastered "Tenrin Ittō-ryū", kenjutsu passed down through the Eastern Digital World, Gaioumon specializes in "silent" swordplay in which it instantly cuts down its opponents without even making a sound. Once prepared for battle, it is almost impossible to approach Gaioumon without leaving any openings. Its Special Moves are restricting the opponent's movements with a tornado unleashed from the "Kikurin" (Senpū Baku), and charging at lightning speed and then bisecting them with the Kikurin, which surges with lightning (Kikurin Issen: Gouraizan). In addition, its secret technique "Touka Seihitsu", in which it cuts down enemies in its surroundings with a single stroke of its sword, is said to quietly bring the battle to an end without them even realizing that they have been cut by their adversary.

戦いに敗れたガイオウモンが、想像を絶する修練の果てに新たな力を手に入れた姿。デジコアに眠る鬼のデータが覚醒し、一刀流へと戦闘スタイルが変わっている。東方のデジタルワールドに伝わる剣術「天燐厳刀流（てんりんいっとうりゅう）」を究めたガイオウモンは、音も無く一瞬で相手を斬り捨てる“静”の剣術を得意としている。一度臨戦態勢に入ったガイオウモンには一分の隙も無く、近寄ることすらままならない。必殺技は「菊燐」から放つ竜巻『旋風縛（せんぷうばく）』で相手の動きを封じ、雷を迸らせた「菊燐」で電光石火のごとく突撃し両断する『菊燐一閃・號雷斬（きくりんいっせん・ごうらいざん）』で確実に仕留める。そして、周囲の敵を一太刀で切り伏せる奥義『刀華静謐（とうかせいひつ）』は、敵に自分達が斬られたことも悟らせず、静かに戦いの幕を引くという。
