The past mercilessly looms as the trials of volume 16 unfold!

With the power of the "Book", the Armed Detective Agency has been branded as a vicious criminal organisation.

All means of escape are being cut off by the mercilessly approaching Hunting Dogs – the military's strongest special unit of Ability Users, led by Commander Fukuchi Ochi!

Up against the Hunting Dogs' enhanced bodies and overwhelming combat skills, can our stray dogs do nothing but be hunted down?

Everywhere, the righteous become the enemy...

To save the life of one, the other must be killed in the next 48 hours. Under the cruel condition, the Armed Detective Agency and the Port Mafia engage in all-out conflict to protect their respective leaders.

As Atsushi and Kunikida struggle to prevent bloodshed, Dostoyevsky interferes as if to mock them. The battle lines are drawn; Kyoka vs. Akutagawa, Ranpo vs. Chuya—!

Is there no way out of this predicament other than to dance to the tune played by the scheming "Devil"...?!!

Despite their mutual hatred, Atsushi and Akutagawa improvise a strategy to foil the Guild, but...

The stormy Guild Arc finally reaches its conclusion!

To fight the guild, the Armed Detective Agency and the Port Mafia must work together...

Following this proposal by Atsushi, a top-level conference is held between Fukuzawa and Mori.
However, as the talks naturally breaks down, Dazai infiltrates the enemy's base to retrieve Q.
Sure enough, Dazai is immediately set upon by Lovecraft and Steinbeck. Then, who should make a dashing entrance but... that man?!!

Dazai's wisdom, Ranpo's deduction, and Atsushi's courage will be put to the test!

His confidence sapped by Q's mental attacks, Atsushi is captured by the Guild with the combined power of Fitzgerald and Alcott's Abilities.

Now on the loose, Q targets a Guild Fellowcraft with a mysterious Ability – Lovecraft?!
