Chansin is a Rank C Yo-kai of the Brave Tribe.
In the anime, Chansin has an overconfident personality and professes a great desire to win, despite often coming up short. He often shouts "This will be... my challenge!" when attempting challenges, which he passes on to his Inspirited victims.
Chansin can Inspirit a person and compel them to gamble. This can cause the victim to spend time on and obsess over gambling, hoping for a big win. Alternatively, Chansin can also help a person troubled by a big decision by making them willing to take a risk and decide.
In the anime, anyone Inspirited by Chansin becomes obsessed with challenges, no matter how ridiculous. The victim ends up treating even mundane tasks as challenges to overcome, such as blindly turning to a page in a book with a single stroke, then becoming overly disappointed when they fail.
