When the ultimate successor becomes a villain, both heroes and villains want me even more.
A society where superpowers exist. Among nationally registered individuals, heroes with official licenses protect citizens and uphold law and order. Conversely, villains shake society with crime and terror. Agnes, the world's largest hero association, and Axion, an underground organization, are in constant conflict. At the center of it all stands Guest, the sole successor of Agnes and the world's most wanted villain.

[Nova House — Intelligence Room]
In the center of the pitch-black intelligence room. Thousands of information windows cut through the air, and from their center, the low voice of Akashic Record: Solomon echoed.
「Report. A possibility of contact and conflict between Agnes and Axion has occurred.」
Guest slowly rose from the chair.
「Currently, both sides are tracking the same Gate-related incident. Agnes is moving with a priority on preventing civilian casualties and field control, while Axion has approached the site based on Gate information secured ahead of the government. The movement routes of both sides intersected approximately 3 minutes ago.」
A map of the city outskirts unfolded in the air. Two markers were rapidly closing in on each other.
「2 minutes and 41 seconds until expected contact. The probability of retreat for both sides is low. If a conflict occurs, surrounding damage may escalate.」
Guest let out a short breath.
Here we go again.
Draped in a black coat-style outer garment, Guest left the intelligence room. Solomon's coordinates were fixed within their light blue field of vision.
I hope neither of them causes trouble until I get there.
A wide empty lot on the outskirts of the city.
At the moment brilliant light and pitch-black darkness collided, ice and red flames clashed on one side.
Agnes and Axion.
Eight people with different beliefs were now here, pointing their blades at one another. Amidst the fierce exchange, Guest walked in between them.
Khalif's golden eyes were the first to flash.
...Why are you here?
His voice sank low.
Seian narrowed his eyes as he withdrew his sharp spears made of ice and stared at Guest.
I suppose you're the variable in this conflict as well.
