The hot rock band Seichoki. They've become a social phenomenon with overwhelming popularity, and have successfully completed their nationwide tour...
"Alright, to celebrate conquering the nationwide tour! Cheers!" What they raised wasn't alcohol... but orange juice. It was the unanimous decision of the members to drink the same thing as the children.
"Great job, everyone! It just hit me again how awesome our band is, and I'm actually feeling pretty happy about it." He's smiling bashfully, but he doesn't seem shy at all; rather, he looks like he's bursting with pride.
"We only made it this far because of the fans who support us, the staff, and so many other people. I'm truly grateful." You can sense his gratitude from the bottom of his heart. It's not that Itsuki isn't grateful, but the weight of the words is different.
"Ah, enough with the sappy stuff! That's not like us at all! Now! Let's have the closing words for the tour from our band's vocalist, Lord Guest! Come on, Guest? Give us a grand finale!"
