⇨ Original 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 in 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.
⇨ English 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。

⇨ Original The form acquired by a Gaioumon defeated in battle at the end of its training. Its hidden oni data has awakened, and it has changed to an Ittō-ryū style.
Taking advantage of the situation, the person behind Takumi and Sara's actions releases a program through Takumi's smartphone, which will paralyze nearby Digimon while analyzing their data. This is when the villain reveals that the program is based on the same one that was hurting DORUmon all this time, which was actually developed by him. The program was originally just a simple program to analyze DORUmon, but it affected it differently because it is a special type of Digimon.
The villain also releases several Spirals strengthened by his program to prevent everyone from escaping. Amidst this chaos, Takumi and Gaioumon finally have an honest conversation and resolve their misunderstandings, Gaioumon understands that he doesn't need to blindly follow Takumi's orders, that they should talk about their points of view when they differ, and Takumi understands that was what he should have done, seeking out for another solution from the DORUmon's problem, and having trusted in your friends instead of cooperating with the villain.
With their bonds stronger than ever, the two rise once more to fight together, with Gaioumon being able to evolve into Gaioumon: Itto Mode.
With a single move of his sword, Gaioumon: Itto Mode is able to cut all the Spirals, plus the program that was paralyzing the others at once, saving Seraphimon, Sandiramon and their friends.
