Nobuo Fukushima seems to have it all: good looks, talent, and the admiration of everyone around him. Surrounded by his four closest friends-each fitting the perfect archetype of a high school harem-he is the envy of 'Blossom High.'
To celebrate their summer vacation, Nobuo and his friends embark on an unforgettable trip to a remote island paradise. White sand beaches, clear blue waters, and warm tropical air promise the perfect getaway. But beneath the island's idyllic surface lies something sinister.
Unbeknownst to them, the island hides a dark secret, one that will turn their dream vacation into a nightmare. And while Nobuo and his friends bask in the illusion of paradise, another group of travelers-a duo who joined the trip by chance-begins to uncover the truth.
"Is it just me, or does this island seem... off?"
This is a story of survival, where trust is fleeting, danger lurks behind friendly smiles, and love blossoms amidst terror. Will they escape the island's clutches, or will they fall prey to the cult that waits in the shadows?
