Kodoku no Yurikago

“That day”—it’s been a year since July 22nd…
The scars from that day haven’t faded.
Mio, who died.
Kazuha, who disappeared.
Left alone, I’ve been drifting through a hazy, half-conscious world.
—Then, one day.
Mio, the girl I thought had died in front of me, suddenly appeared again—
……
Turns out, she’s just a lookalike. A completely different person.
She said she’s a transfer student.
But come on… that’s not something that just happens, right?
