You go all-out and buy front-row tickets. You meet Kirika at the appointed time and place, and hand her her ticket.
"Wow, you didn't have to go all-out like that."
You buy some snacks to share and make your way to your seat. A few songs into Hayashibara's set, she sings "Motto Motto Radical Fight!" and something between a mosh pit and a brawl breaks out. Kirika acts quickly and saves you from being crushed by the crowd.
Convinced that you really can't handle yourself very well in dangerous situations, she calls it a night. "Thanks for inviting me. Be careful on your way home."
