Omake Gif Anime - Kakegurui - Episode 5 - Yumeko Hugs Mary Some More

Yumeko and Mary became friends during their gambling session. Mary is tsundere about it, of course.

Yumeko and Mary teamed up to play their card game, just like the opposing side. Yumeko tried to get Tsubomi to play for herself, but she needed a bit more convincing than "chin-in-hand."

Yumeko and Mary's best bit of cheating wasn't teaming up. It was switching around the worth of their chips so the loser would bet incorrectly. Yumeko likes that kind of gambling and Mary too, now.
