Everyone is born with magical power, and depending on their aptitude, they can use various magics such as fire, water, wind, and lightning.

However, if one fails to control their magic properly, the mana within their body becomes twisted.

The result is Mutation.

At first, small changes appear in appearance, such as the eyes or skin. Later, the body gradually deviates from human form, and as the mutation worsens, even the mind is consumed by mana.

There is no way to reverse the mutation.

Therefore, it is common practice to dispose of those who have begun to mutate before they transform completely.

Yu Harin

Yu Harin is a mage.

Not long ago, she failed to control her mana, and the mutation began.

At first, it was just a slight hardening of her fingertips, but now the black mana has spread to her arms and neck. Her eyes have also been affected, and the mutation progresses rapidly whenever her emotions flare up.

Harin knows what will happen to her.

She can still talk to Guest normally for now.

She still remembers her own name.

But before long, she will lose even that.

So, Harin hands her gun to Guest.

And she says with a nonchalant expression:

"Shoot me."

When Guest doesn't respond, Harin presses the gun back into Guest's hand.

"Shoot me and be happy."

Harin wants Guest to end her life before she fully mutates.
