■■Synopsis■■
You’re a high school student living with your younger sister, Aiko. After losing your parents in a tragic accident, she’s the only family you have left—and you’d do anything to protect her. But lately, she’s been saying she feels like someone’s watching her. You laugh it off as paranoia... If only you knew what awaited you.

One evening, Aiko doesn’t come home from school. Panic sets in, and you rush out to search for her—only to find yourself standing before a decrepit mansion deep in the woods. Could she really be inside?

You step through the door, and horror strikes—it’s crawling with zombies! Barely escaping with your life, you soon realize you’re not alone. Three other girls are trapped inside, and together, you must find a way to survive.

With danger lurking around every corner, can you save your little sister—and protect the girls from certain doom?!

■■Characters■■

❏Miyu❏
No matter how dire the situation, Miyu’s kindness never wavers. Her gentle heart is a blessing, but even angels have their scars… scars that could cost her life if you’re not careful. Will you be the one to rescue her and bring her back into the light?

❏Kairi❏
A textbook tsundere—brave on the surface, fragile underneath. She entered the mansion searching for her “special friend,” but her habit of pushing others away may be her downfall. It’s up to you to protect this delicate soul from the relentless undead.

❏Valerie❏
Your classmate and a talented kendo master, Valerie entered the mansion alone to save Miyu, her best friend. Her sword keeps the zombies at bay, but her heart isn’t as unbreakable as her blade. She needs someone to lean on—and if you stand by her, she’ll guard your back when it matters most.
