His team was the previous National Champions of Japan before being defeated by Ren Suzugamori's Team Asteroid. His Avatar Unit is Super Dimensional Robo Daiyusha.

Speed: At least Massively FTL+ with Units (The souls of Cardfighters are far inferior to the Units of Planet Cray and explicitly require them to battle in cardfights, which would include Takuto's soul, which traveled past numerous stars in seconds to reach Planet Cray and all cardfighters transport their souls to Planet Cray when participating in cardfights; Comparable to the speed of Yuri and Kamui's Units)

Standard Equipment: Vanguard card deck, Vanguard Units
Optional Equipment: None
Intelligence: At least Gifted. Gai is a very skilled tactician and strategist, being able to easily develop strategies and successfully pull off strong combinations and battle formations to make use of his Units skills and abilities to their fullest extent. Battling on Planet Cray reinforces his already great intelligence by being able to possess Units, enter combat as the Units, and lead other Units into battle against other Cardfighters. Gai is recognized early to be among incredibly experienced cardfighters alongside his teammates, being the previous National Champions of Japan before Team Asteroid dethroned them. Gai is very skilled enough to defeat many skilled Cardfighters, but sometimes fails to win for lacking a winning image. The Units Gai uses are also very skilled tacticians and strategists by participating in numerous battles with Gai.
Weaknesses: Gai tends to enter cardfights without clearly picturing how he will win, which can get the better of him and prevent him from winning at times. Cardfighters have to ride Units in chronological order, they cannot skip a grade when riding, like going from a Grade 0 Unit to a Grade 2 Unit. Cardfighters in most situations cannot summon Rear-Guard Units that exceed the grade of their Vanguard for offensive and defensive purposes. Cardfighter's must sacrifice Units when using them for defensive purposes | None notable
Notable Attacks/Techniques:
*Imagination Manipulation: All Cardfighters use the power of imagination for various purposes and to different extents in the game of Cardfight!! Vanguard
*Soul Projection: In the game of Cardfight!! Vanguard, all Cardfighters can use the power of imagination to project their spirits onto the surface of a planet that is very similar to Earth in the Vanguard universe, Planet Cray.
*Summoning, Possession, Transformation, Mind Control & Fusionism: In the game of Cardfight!! Vanguard, all Cardfighters cannot only summon but possess one of the Units living on Planet Cray for their spirits to reside in after projecting them onto Cray's surface. Upon summoning and possessing the Unit, the Cardfighters soul takes the Unit's form and can use them to battle other Cardfighters during a cardfight. This is otherwise known as a "Ride", where Cardfighters use Units to become "Vanguards". Cardfighters are also able to summon the creatures of Planet Cray to fight on their behalf as allies. This is otherwise known as a "Call", where Cardfighters summon Units as "Rear-Guards". In most situations, Cardfighters can only summon Units who's grades are equal to or lower than the grade of their Vanguard's. For example, if a Cardfighter uses a Grade 1 Vanguard, they can only summon Grade 1 or Grade 0 Units for support. They cannot summon Grade 2 or Grade 3 Rear-Guard Units.
**Guarding: To go along with being able to summon Units, all Cardfighters in the Cardfight!! Vanguard game can also summon Units for defensive purposes. They can sacrifice Units to protect the Vanguard or other Rear-Guard Units from being harmed or destroyed by opponents by using the power given in shield values which are combined with the Vanguard's power. This can also be done using Perfect Guard Units that can negate the opponents' attacks. Guarding can be accomplished by either summoning the Units or using Units already in battle with you that have the "Intercept" skill. While Grade 3 Units cannot be used as defensive Units in the game itself, this would fall under as nothing but card-game mechanics.
***Power Draining: Whenever Cardfighter's summon Units for defensive purposes, they can also weaken the power of the opponents' Units that are attacking in efforts to weaken their attacks. The defensive power of the Unit that's being used as a guard is directly subtracted from the Unit that is attacking. For example, if a Cardfighter uses a Unit that has 10,000 power for a shield value, and the opponent is attacking with 15,000 power, the total amount of power the opponents Unit will have left is 5,000 power, weakening them. However, only Units with shield values (Grade 0s, 1s, 2s, and some 4s) can weaken the power of opponent Units. So Grade 3 Units and Perfect Guard Units would not be able to drain the power of opponents when used for guarding purposes.
*Soul Manipulation: In the game of Cardfight!! Vanguard, there is a mechanic that all Cardfighters make use of with their Units known as "The Soul". "The Soul" is when and where Units are placed underneath a Cardfighters Vanguard that is currently in use, making it a "soul-stack" and when the number of Units in the soul reaches a certain point, they can be sacrificed for the price of activating different abilities. There are two methods on how to add Units into the soul. One method would be for Units to be ones that have been previously rided on. For example: if a Grade 3 is rided ontop of a Grade 2, who is rided on top of a Grade 1, who is rided ontop of a Grade 0 starting Vanguard, the lower Grade Units will be within the Grade 3 Vanguards soul. The second method would be to use a skill called "Soul Charge" where Units get added into the Vanguards soul. In the game of Cardfight!! Vanguard, "The Soul" is also considered the soul of any Unit that is being used as a Vanguard for a cardfighter, and when Units enter or are placed within "The Soul", they become souls themselves. Using "The Soul", Units can use soul manipulation to multiple degrees. They can use it to send themselves into and out of the soul, soul absorption to "Soul Charge" other Units as Vanguards, or soul destruction to destroy Units within the Vanguards soul through a skill called a "Soul Blast".
*Boosting: This is a skill exclusively for Grade 0 and Grade 1 Units in the Cardfight!! Vanguard game. When in the rear-guard as support Units, Grade 0s and 1s can give their power to other Units to boost their power further.
*Triggers: In the game of Cardfight!! Vanguard, there are Grade 0 Units who have unique abilities called Triggers. Whenever a Vanguard attacks or takes damage from attacks, Cardfighters reveal cards from their decks during battles in an attempt to get a Trigger. There are 4 kinds of Triggers in Vanguard and each Trigger has a different effect, along with a power boost to be given to the Unit of choice. There are Draw Triggers, Critical Triggers, Heal Triggers and Stand Triggers. The only trigger that can be discarded as nothing but game mechanics would be the Draw Trigger Effect. Heal Triggers would be Healing Hax, Stand Triggers could be treated as a kind of Stamina Inducement to allow Units to attack more in succession, and Critical triggers would be given Damage Boost. Also, whenever a Cardfighter reveals a Trigger during a Drive or Damage check, it's the equivalent to the cardfighter summoning the Trigger Units to give them the Trigger Effect on Planet Cray.
*Existence Erasure & Resistance: In the game of Cardfight!! Vanguard, all Units from Planet Cray can completely erase Units with every kind of attack they unleash in battle. When Units are destroyed, they get sent to the Drop Zone, which is the direct equivalent to Units being completely destroyed when they battle between each other on Planet Cray. The cardfighters themselves don't have existence erasure, but their souls have resistance for being able to remain unaffected by their Vanguards being erased at the end of a cardfight.
