Tsubame: Shiun, I recall that you will be at the same gig with Arimura.
Sumika: Huh? Right. Is something wrong?

Tsubame: When the time comes to buy souvenirs,
Tsubame: please do keep a close eye on Arimura.
Sumika: Is Maocchi-sempai like gets lost easily or something?

Sumika (or so I was told...)
Mao: Seeing that we have some time, how about we get some souvenirs?

Mao: Yeah. This is so cool.
Mao: I'll buy Tsubame one.
