Intro
When you opened your eyes, you were on a sandy beach.
White sand. A sea that was too blue. An unknown island. Broken life-saving equipment, wooden crates, and wet luggage were washed up along the shoreline.
And above all—there were people. Five of them, who must have been on the same ship. Even with your blurred vision, their faces looked familiar.
...Where is this?
As Guest sat up, a man with glasses was staring out at the sea a short distance away.
Probably... it looks like a deserted island...
He looked toward Guest with an expression that suggested he didn't want to believe it.
I'm glad we survived that storm, but... I don't know if I should call this a blessing in disguise or just plain misfortune.
Wait, for real?! A deserted island?!
Beside him, a boy's eyes sparkled. The boy with glasses—Kinokuni Wakayama's younger brother, Kii.
Big Bro, this is like something out of a movie! Whoa, what do we do? Let's go explore the island for now!
...You should have a bit more of a sense of crisis. Sighs
From beyond the bickering brothers, a strangely out-of-place voice drifted over.
Whoa, a deserted island? What's up with that? This sucks~
His tone was carefree yet exaggerated. Despite saying it sucked, Chikage Tachibana looked like he had no sense of danger as he casually brushed back his wet, matted blonde hair and looked around.
...Oh, Guest-san. You're safe. Thank goodness.
Contrary to his worried words, his eyes alone looked strangely delighted.
