Background

Daigo was a Victory Team member before joining the Chat Group. He regularly fought monsters, piloted fighter jets, and was often left to repair the aircraft after crashes. 4

Lu Changsheng personally visited Daigo's universe and identified the Light Gene Factor within him as a special constitution comparable to a Light Body. This factor both supports Daigo's transformation into Tiga and gives him an unusual advantage in cultivation, allowing his human body and transformed body to strengthen each other. 17

Following the Gatanothor crisis, Daigo's identity as Tiga remained hidden because the battle ended without his defeat or humanity's light being required to restore him. 48 He later retired from the Victory Team era after its members moved into new roles, but continued protecting other worlds and training in space. 206 318

A Tiga stone statue Daigo discarded during his Clone Technique experiment traveled into the super-ancient era and resonated with a distant ancestor. That ancestor transformed into a silver-white Tiga and saved the Luluye Empire from Golza, creating a possible lead to Tiga's origin. 102 130

Appearance

In human form, Daigo conceals his identity and carries a Spark Lens to transform. As Tiga, he appears as a towering tri-colored Giant of Light with golden armor-like details and a blue chest marking. 17 83 249

• Normal Tiga — Daigo's standard Giant of Light form. 17
• Red Tiga — A power-oriented form with increased attack power and physical defense. 251
• Shining Tiga — A high-output form wielded through the Shining Spark Lens or briefly reproduced through Daigo's own power. 45 204
• Demon Back Tiga — Tiga enhanced by Demon Back and Power Nullification, greatly amplifying the two abilities' effects. 346 381

Personality

Daigo is warm-hearted and instinctively protective. Although he had no obligation to intervene in Mebius's battle with Dinuzoru, he transformed immediately to help. 83 When Gatanothor's black fog engulfed TPC, he chose to face the threat alone despite knowing how dangerous it was. 43

He treats power as a responsibility rather than a reward. Daigo continuously trains because he believes greater strength is necessary to protect the people and worlds he cares about. 249 318

Daigo is also prone to unconventional ideas, particularly involving cultivation and mobility. His proposals have included flying by stepping on his own feet, hiding blades in his shoes to fly, and stepping on air directly. 41 61 65

Abilities & Skills

Light Gene Factor and Transformation

Daigo's Light Gene Factor resonates with the Spark Lens's Light Power to transform him into Tiga Ultraman. It also assists his Qi Refining and becomes stronger as he cultivates. 17

• Can transform through the Spark Lens into Tiga. 17
• Stores some cosmic energy absorbed by Tiga within the Spark Lens. 17
• Transfers part of Tiga's accumulated power back into Daigo's human Light Gene Factor. 17
• Can sense the light within other Ultramen, allowing him to identify Gen Otori as Leo before Leo revealed himself. 173

Qi Cultivation and Tiga Breathing Technique

Lu Changsheng taught Daigo both Qi Refining and a Breathing Technique tailored for Tiga. The latter allows him to draw cosmic energy while transformed. 17

• Cultivates in both human and Tiga forms. 17
• Uses the Breathing Technique in space to strengthen himself before combat. 42
• Delays Tiga's red-light energy warning during battle. 42
• Uses his cosmic-energy absorption and light power to cultivate spiritual crops on Mars. 308

Shining Tiga

Daigo received the Shining Spark Lens following the Gatanothor battle. He later developed the ability to reproduce a temporary version of Shining Mode through his own power. 45 204

• The Shining Spark Lens enables his transformation into Shining Tiga. 45
• His self-generated Shining Mode has the form's abilities but is temporary and requires him to release his power at its peak. 204
• Wields the Shining Ring Shield, which can defend against a wide range of attacks. 318
• Treats Shining Mode as a trump card rather than a form to use at the start of every battle. 318

Spatial Travel

Daigo can move across battlefields, planets, and eventually universes through his own power.

• Teleports between monster attacks across Earth. 42
• Opens spacetime tunnels to return to his original universe. 202
• Can break through the barriers of multiple Ultra Universes with a single strike. 336

Combat Techniques

• Energy Disc — Formed a rapidly rotating purple energy wheel capable of distorting surrounding space through heat and cutting power. 83
• Power Nullification — A perfected martial principle that lets him redirect or evade force; after being integrated into Tiga, it can nullify more than physical force. 346 381
• Demon Back — Enhances his physical strength and stamina; in human form, it allowed a single punch to blast apart a Martian sandstorm. 346
• Absolute Destruction — Assimilated Tartarus's technique and used it to kill Diablo. 348

Daigo experimented with a Clone Technique that produced a separated Tiga body. The body can be controlled by people who share his ideals. 102
