Abilities
Prior to his training with the late Yukimura Katsuki, it is implied that Tatsurou's skills were sub-par with other Taimanin in his academy. Mostly, his abilities were more fitted for stealth than combat. After his training with Yukimura, he slowly hones plenty of his abilities to mastery and becomes a force to be reckoned with: a powerful ninja who lays retribution upon evil.
 * Magi physiology / sensitivity to chi -
 * Wind elemental manipulation –
 * Master swordsmanship – Initially, he was unskilled in handling his sword, such as being unable to lift it high enough to strike. However, after training, he can properly his sword and flow accordingly with the movement of his enemies to predict when to attack or block with it.
 * Supernatural agility – Tatsurou is capable of evading or dodging attacks in a split second during close combat or from long range distance. It is done through his inherited technique from his father's side of the family, the Art of the Wind Dance (風舞の術), focused on swiftness and agility as opposed to brunt force.

Weapons
Tatsurou is armed with his signature sword called the Fuujigiri (風刀切), a silver katana with the length being 3/5 of an average person's height. However, the Fuurai is just a mask to its true form that he unlocks during his battle against the Dark Horror army: the Wind Wing Blade Doujigiri Yasutsuna (風翼刀・ 童子切安綱ドウジキリ・ヤスツナ). Sometimes, he would also use the Doujigiri simultaneously with the Flame Dragon Katana Onimaru, which he possesses after Yukimura's death.

Attacks

 * Ninja Arts - Emerald Tornado (忍法・綠寶竜巻) – Tatsurou's signature ninja art; it is an offensive technique in which the user unleashes a large tornado of green turbulent winds extremely fast and strong that they induce damage to the afflicted enemy. The force of the tornado also has the enemy flying miles back or above.
 * Super Ninja Arts - God Thunder Wave (超忍法・神雷流) – Tatsurou's finishing move; he concentrates his chi into his body and transforms into a stream of light-green energy in the shape of a Chinese dragon covered entirely in electricity. He flies upwards and charges towards the opponent, colliding in full force like lightning and utterly demolishing it.
 * Combined Technique - Wind and Fire Obliteration (合体奥義・風火激破) – Tatsurou's other finishing attack; he harnesses the wind and fire powers of both the Doujigiri and the Onimaru respectively and slashes his enemy with both blades. Alternatively, he fires a tornado from the Doujiri and a stream of fire from the Onimaru, with the two merging to form a massive fire tornado with the force of a hundred volcanoes which comes at the enemy and completely burns them away.
 * Combined Technique - Rumbling Thunderstorm (合体奥義・轟天風雷) – Tatsurou and Yukikaze's combo attack, which is a combination of the Emerald Tornado and Blessing of Lightning. The two Taimanin position, with Yukikaze crouching and pointing her guns at the target and Tatsurou standing behind her. Yukikaze fires full-powered streams of lightning at the opponent, while Tatsurou unleashes two large tornado from his palms. The lightnings and tornadoes merge to form an extremely powerful and turbulent force comparable to a thousand thunderstorms. The combined lightnings and wind forces from the thunder tornado then destroy the opponent.
