Wow. Kyuu backstory, and then some. And that is just the beginning.

(And my guess from the previous one about that revelation turned out to be false.)

And it’s all interconnected!

… what’s up with the prisoners, both of them…

… and wtf is that case beginning at the end? Oh well, I’ll rate that later… maybe… this volume has so much backstory and more greatness in the first majority of chapters…

THE SAFE, THE CARD, AND KYUU’S HIDDEN PAST
While exploring the school’s old building, Kyuu and Megumi uncover a forgotten safe. Inside lies a weathered business card—belonging to the very detective who once rescued Kyuu during a kidnapping and gave him the "Detective Handbook" that inspired his journey. As they confront Mr. Dan with their discovery, he is overcome with emotion, revealing a deeply personal connection. The curtain is lifted on Kyuu’s mysterious roots, tying his fate more closely to the world of detectives than he ever imagined.

A CODE FROM CERBERUS: THE ENEMY WITHIN
Nanami gives Class Q a masterclass on disguise before taking them to visit Cerberus—the elusive Pluto executive and master of hypnosis now imprisoned after the Kiriyu case. When asked about the Pluto agent hiding within DDS, Cerberus refuses to name the infiltrator directly. Instead, he offers a cryptic code for Class Q to decipher and warns them of his imminent escape. The message is clear: someone dangerous is hiding in plain sight, and the real game is just beginning.

Sosok Q memang nggak sekeren Shinichi. Tapi genre nya yang bikin gw tertarik utk baca komik ini.

Tapi gw baca ni komik cuma nyampe di level ini gara gara kemaren gak ada waktu utk ngerental. Huffff
