Oricon Comic Ranking Summary

3rd place: That Time I Got Reincarnated as a Slime Extra Story: How to Spend a Certain Vacation

After the successful conclusion of the Opening of the Nation Festival, peaceful days finally return to the Jura Tempest Federation.
During this calm, Veldora suddenly proclaims his desire to “develop beast magic.” Beast magic—created by the great sorcerer Benares in the legendary 3×3 EYES—is a magic system that could only be described as every man’s romantic dream.

Rimuru doubts whether such a thing could even be realized in this world, but with encouragement from Luminous, he decides to head to the “Magic Tower” to develop a new spell.

Thus begins a magical research journey—a “paid vacation”—undertaken by Rimuru, Veldora, and Hinata!

The volume also includes a special interview between manga artist Yuzo Takada and the original author Fuse, as well as a newly written short story set after the novel’s conclusion!

2nd place: That Time I Got Reincarnated as a Slime 23

With Rimuru’s return, the forces of Tempest are filled with renewed determination.

In the midst of this, Rimuru receives shocking news from Velzard—
information that could fundamentally overturn the nature of the entire conflict.

Meanwhile, Ivarage begins to make troubling moves of his own, plunging the situation further into chaos.

A true all-out war.
As everyone is pushed to their limits, the fate of all rests upon a single slime.

The immensely popular reincarnation fantasy finally reaches its main-story conclusion!

1st place: Classroom of the Elite: 3rd Year Arc 3

This year’s uninhabited island special exam is a class-versus-class survival game!

In their final summer as third-years, the students face a survival match using paintball guns.
The island is divided into 15×15 grid squares, and students must move through them while gathering appearing supplies and ammunition, battling other classes as they compete.

The first class to be completely wiped out will face penalties involving the selection of expelled students—making strategic offense and defense absolutely crucial.
Students assigned the “commander” role can check GPS data every five minutes, seeing all students displayed in their class colors, meaning coordinated group action is a must.

“How will you move, Ayanokōji?”
“We should be one step ahead… and yet, I can’t help but feel nervous.”
“Ayanokōji-kun won’t lose. No… I won’t let you lose.”

The four-day, three-night special exam reaches its decisive conclusion—!?
