Rebuild World (Manga) Volume 12

Seeking invaluable treasures from an untouched ruin, the Druncam rookies join the crowds of hunters flocking to Yonozuka Station. But a sudden rush of monsters floods the ruin, trapping them within and splitting up Katsuya and Yumina! To save his comrades, Katsuya—hot on the heels of his Faustian bargain—plunges into the heart of the ruin. Meanwhile, Yumina enlists Akira's help to find her crush—though Akira himself could care less about Katsuya's fate. But can they survive the secret horror that yearns to escape the ruins? And why is Shikarabe, the Druncam veteran, seeking Akira's aid for an under-the-table mission?
