Chansin is a lean humanoid Yo-kai with black skin and eyes with yellow sclera. He wears an attire typical of a wanderer, with a red and black color scheme, and sporting traditional japanese card artwork as shoulder pads, as well a straw hat with two ribbons, red and teal in color.
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.
Chansin appears under vending machines and cars everywhere on Shopper's Row, and is one of the Yo-kai that can appear in the Yo-kai Spot "Ride!" in the same location.
Alternatively, he is befriended automatically while completing [Request #36] "Crane-Game Mania", given by the clerk during the day in Arcadia Arcade in Downtown Springdale, starting at Chapter 6 after unlocking Rank C. To complete the request, simply use the Yo-kai Lens near Matt to find Chansin.
Lastly, Chansin can be freed from the Crank-a-kai with a Red Coin.
Chansin can be found in the Seaside Cave in San Fantasticnime
Yo-kai Watch animation series
Chansin debuts in EP075, Inspiriting Nate's classmates and prompting them to perform ridiculous challenges. After Nate identifies him, Chansin admits his own gambling impulse and that despite Inspiriting countless victims, he's never won once. Nate ends up summoning various Yo-Kai to set up challenges for Chansin, but his horrible luck ends up failing him every time. Nate eventually has Chansin join a variety show the group was watching earlier, where Chansin is challenged to pick a piece of sushi that doesn't contain wasabi. After he predictably fails, his exaggerated, pained flailing "wins over" the audience's laughter.
Chansin's shoulder pads are shaped like Hanafuda cards. When the Sakoku policy in 1633 isolated Japan from the world, the Hombre playing cards imported by the Portuguese were banned; new games were invented to replace them, which in turn would be banned again once they got popular enough in the gambling halls. Eventually the laws became less strict, and a new game called Hanafuda was created, based on matching images instead of counting numbers for scoring. Still, all the years of repression had killed the populace's interest in card games by then. However, in 1889 one Fusajiro Yamauchi founded a company producing handmade Hanafuda cards printed on mulberry bark, and slowly but surely playing cards became popular again. That company was called Nintendo Koppai, the root of what would later become the videogame company Nintendo.
