Who is Komasan's younger brother in Yo-kai Watch?

Komasan's younger brother in Yo-kai Watch is Komajiro. The two are lion-dog Yo-kai from the Charming Tribe, introduced as siblings whose lives change when they leave the countryside for the city.

Komasan is the older brother and originally guards a rural shrine. After the shrine is demolished for construction, he travels to the city and struggles with its noise, crowds, unfamiliar customs, and his enthusiasm for soft-serve ice cream. Komajiro adapts much more quickly and is generally more outgoing about city life.

The names can be confusing because several characters have similar Koma-based names. Komasaburo is not Komasan's younger brother; he is an adoptive human brother introduced in the film Yo-kai Watch: Enma Daiō to Itsutsu no Monogatari da Nyan! Komajiro is also a recurring anime character and appears alongside Komasan in other Yo-kai Watch stories.
