Toraoh originates as the son of Doakudar and the Demon Prince of Makai, positioned as Wataru Ikusabe's competitive rival before their rivalry escalates into mortal enmity. Through repeated encounters, Toraoh learns the value of friendship, ultimately allying with Wataru in the final battle against Doakudar and the Dark Dragon. During this conflict, Toraoh sustains fatal injuries after creating an opening for Wataru to strike the dragon's weak point. The queen of Mt. Soukai later reverses his death, resurrecting and restoring him to his true identity as Shoryushi, her actual son. Despite this transformation, Toraoh's spirit persists as a separate consciousness within Shoryushi due to their established bond.

In *Mashin Hero Wataru 2*, Toraoh joins Wataru's party late in the series on Star Mountain's 6th World. This season highlights their deep friendship, with both characters regarding each other as best friends. Toraoh aids Wataru and Umihiko in the final confrontation against Doakuda before reverting to his original identity.

During *Super Mashin Hero Wataru*, Toraoh reunites with Wataru in Mt. Soukai's 4th Realm but initially lacks memories of their past due to stolen consciousness. Blizzarbeth, the realm's boss, brainwashed him into serving as a replacement for her deceased son. After Wataru defeats Blizzarbeth, Toraoh regains his memories but is kidnapped by Dohdo. King Donarukami forcibly re-brainwashes him into becoming Wataru's enemy, exploiting Toraoh's belief that Wataru killed Blizzarbeth. This conflict persists until the 6th realm's climax, where Toraoh returns to normal after Seijyu sacrifices himself to restore Toraoh's conscience. Doruku later revives Seijyu by reopening his closed heart.

Supplementary media, including the radio drama *Mashin Hero Wataru 3: The Story of Toraoh* and the novel *Mashin Hero Wataru Tiger King Legend*, expand on Toraoh's background, identity, and experiences beyond the anime series.

Physically, Toraoh is a young boy with blue eyes and shoulder-length blonde hair. His personality is energetic, headstrong, and stubborn, often driving him to accept challenges without hesitation. While his ego occasionally leads to impulsiveness, he demonstrates deep kindness and loyalty toward Wataru and other friends.

Toraoh's role or development in *Shin Mashin Eiyūden Wataru: Mashinzan-hen* is not detailed in the provided information.
