Yokoi (voiced by Kana Hanazawa) sits in the last row of the class. Her neighbor Guan (voiced by Hiro Shimono) is a weirdo who always skips class - playing all kinds of amazing games in an amazing way, from dominoes, shogi, go to table golf, and even polishing and modifying the table. Guan's little tricks in class have completely exceeded the scope of "little tricks", so that Yokoi, who has a serious personality, can't turn a blind eye to his behavior. Although she wants to listen to the class seriously, she will be attracted by Guan's little games every time. She often stops Guan with her eyes or whispers, so she is often criticized by the teacher. However, Guan does his own thing and has mastered the trick of destroying evidence before the teacher finds out. This animation is 8 minutes long per episode, showing Guan's various "little tricks". With Yokoi's complaints, this pair of neighbors brings the audience a relaxing and hilarious story in class.
