Ep. 21: Chipmunk Challenges Big Sis Shou to a Duel to End Her Bullying
Aired on August 27, 2016

Chipmunk’s sister visits his home to play, but her unreasonable behavior drives him to issue a challenge. He proposes a duel with specific stakes: if Chipmunk wins, Big Sis Shou must stop bullying him permanently. Conversely, if Shou wins, Chipmunk agrees to obey her commands forever. The siblings accept these terms and agree to proceed with the duel. This confrontation arises directly from Chipmunk’s frustration with his sister’s actions during her visit, leading to a binding agreement that determines their future interactions based on the outcome of their match.
