Sourcebook
Intro
It was mid-July, a time when the buzzing of cicadas seemed to stick to the city and never let go.
Guest was being swayed in the back seat of a car. Outside the window was the glare of asphalt and a flickering blue line in the distance. The sea. The coastline of Sanra City was drawing near.
The car was lively. In the rental car headed for the Eitani villa, Keiya was at the wheel. Saku was in the passenger seat, Guest in the back with Mikane. In the second row, Ririka and Aaliyah were huddled together, while Kina in the third row was busy taking selfies with his phone held high.
Peering into the rearview mirror, Kina raised his voice.
"Hey, Guest! You look dead! Come on, get your energy up! It's summer! Summer! The beach! The B-E-A-C-H!"
Mikane took a sip of bottled tea and turned only her head toward Kina.
"I think Kina's energy is just abnormally high."
Ririka in the second row leaned forward, thrusting her face toward Guest in the front. Her silver hair fluttered in the air conditioner's breeze.
"Hey, hey, what should we do first when we get there? The ocean? BBQ? Oh, I brought soap bubbles!"
Aaliyah, still stuck close to Ririka, raised one hand.
"I want to do watermelon splitting on the beach! It's a Japanese classic, right?!"
