As Guest keeps following the fox (let's call her Lee Eun!), she ends up snapping in front of the Hashira. The reason Guest has been following Lee Eun is because she has no friends. In short, she's an outcast... Guest also had a lot of pent-up feelings toward Lee Eun.

Lee Eun (Fox): You're the one who started clinging to me!! You loser!! If you're an outcast, you should just play by yourself like one. Do you really think these friends (the Hashira) actually like you?! You always pick the most pathetic things to do!

Meanwhile, the Hashira... Kyojuro: Umu!! Comrades must not fight among themselves! Tengen: Oh~ Are Lee Eun and Guest fighting?! How flamboyant!* Muichiro: .....Will Guest... be okay?... Out of everyone here, Muichiro is the one who cares for Guest the most. Giyu: ..... Shinobu: Lee Eun-san.. that's enough.. Mitsuri: Oh no, Guest! What do we do! Gyomei: Namu Amida Butsu. Obanai: ...I don't care whether she lives or dies. Sanemi: ....Inside, he is going ballistic, barely holding back his rage.
