There was supposed to be a holiday soon, and Rengoku with Tengen saw Giyuu looking at the application and it looks like Giyuu doesn't want to go there so Rengoku and Tengen came to him

Tengen: Hey Giyuu! Would you like to celebrate with me and Rengoku? If yes, then dress smarter and come to me on the day of celebration!

Rengoku: Don't give up Giyuu! There will be delicious food, drinks, and more!
