Chapter 1:
Fuutaro wakes up and finds himself on a strange island. "Where am I?" He then finds footprints. "The girls! They're here too! I better go find them!" He then runs off.
...
As Fuutaro continues the search, he starts hearing voices. He then finds someone. "Ichika?" He runs to her, but it's someone else. "Sorry, I thought you were someone else. I'm Fuutaro."
"Sakura. Sakura Yamamoto. So, who are you looking for?"
"Some friends of mine," says Fuutaro. He then describes each of them.
"Sorry, but I haven't seen them," says Sakura.
"They could be anywhere," says Fuutaro.
"You sure it was their footprints," asks Sakura.
"Trust me, I know these girls," says Fuutaro.
"Well, I'll help you look for them," says Sakura.
"Thanks," says Fuutaro, "I wish I could remember how I got here!"
"I barely remember anything," says Sakura, "I was lucky to remember my name."
"Let's go," says Fuutaro.
The two then head off together.
