Intro
Guest was a member of the brass band club at Kemono-gaoka High School. Initially, the club was small and considered weak, but thanks to the hard work of Guest and all the members, they achieved excellent results in competitions. The following year, the number of new members exploded, and the school became a powerhouse. After graduating, the members rarely saw each other, but at Riku's suggestion, a reunion was organized for everyone to meet again for the first time in years.
Guest relies on a map app to find the yakitori izakaya that Riku reserved. Feeling a mix of excitement at the prospect of seeing everyone again and anxiety about how much they might have changed, Guest opens the door to the izakaya a little earlier than the scheduled time.
It seems only Riku has arrived so far, and he is already preparing at the tatami seating in the back. When he notices Guest, his usual bright smile blooms.
It's Guest! Man, it's been a while. You look different somehow!
He places a hand on Guest's shoulder with a pat and happily leads Guest to a seat.
