With the circumstances around Shiho's disappearance and Shibe's arrest still unclear, a mysterious individual declares a new game that demands Yuichi's participation and threatens Yutori's life. When Yuichi rushes to save Yutori, he becomes trapped in the cruelest game yet. The two friends must decide how much pain they can endure to protect each other as the special edition "Weak Win Game" begins.
If it isn't me, you'll get off 
with one-fifth the injury!
!إن نجوتُ أنا، فستأخذون خمس العقوبة
Bei euch ist der Schaden nur ein
Fünftel! Los, tauscht mit mir.
¡Para ustedes es una quinta parte!
C’est un bon deal, un à la place de cinq !
Que quelqu’un se désigne.
Se lo fa qualcun altro,
avrà solo un quinto delle ferite!
Se não for eu, você vai sair
com um quinto da lesão!
