Video games

Anime series


Siro is a lion-like Yo-kai who is a recolored version of Blazion where his color scheme is gray, white, and fainted teal or neon blue. It's mane is mostly white, while accentuating it with some teal color, to make it look like flames. Similar to Massiface, Siro has a small white scar on his forehead, to represent wounds from battles. It has neon blue swirls on its arms, and its skin color is a pale gray. Its eyes share the color scheme with the rest of it: its eyes are gray and neon blue. Siro is wearing a white top and dark gray pants with neon blue hems.

As his medallium bio says, he brings out the best of those he inspirts, becoming shining lights for the future.

In the anime

Siro debuts in YW006. Nate summons Blazion to talk to Siro, but they soon both inspirit Nate, making him pick his nose eagerly. After Siro gives Nate his ark, Katie was revealed to have looking through her window and saw Nate the whole time. She immediately closed her window.


  • "Siro" is the word shiro (Japanese: "white") spelled with the old Nihon-shiki romanization system.
  • "Todorokijishi" translates as "roaring lion".


  • Todorokijishi is the first lion Yo-kai who uses the Japanese word for "lion" in its name.
    • It is also the only one based on Blazion to do so.
  • Todorokijishi's name is written somewhat inconsistently in official media, either using all kanji, or the "Todoroki" part of this Yo-kai's name being written in hiragana.
  • Siro's "random" nicknames in Yo-kai Watch 2 are: Empawrer, Leo, Silvine, and Cotton.
