Quirk:  Mirror World

Type:  Emission

Range:  30 meters

Quirk Description:  The quirk "builds" a new possibility into the world. The user focuses their attention onto a specific point to create a glass-like material that creates the new possibility around the target. This material will shatter under various circumstances(see Weaknesses).

Weaknesses:  The quirk heavily depends on the user's mental state. If they cannot handle the stress, all instances of Mirror World shatters, causing an explosion or implosion of extremely hard glass-like shards around the target of Mirror World.

The user must understand the aspect that they would want to create. Impossible creations such as "omnipotency" or "instant death" are not possible.

Furthermore, the durability of Mirror World greatly weakens once anyone, foe or ally, notices the instance of Mirror World(even if they do not directly see it).

For instance, the user imagines themselves as a literal tank(the vehicle). Due to the sheer demand of the creation, the stress of the creation would almost immediately cripple the user. In addition, if they do activate the ability, the people around the user  would almost immediately notice the instance, which causes the shattering of Mirror World.

Mastery:

Through intense practice of the mind and imagination, the user may be able to create the possibility and sustain it for a great duration, even with the Weaknesses(excluding the impossible aspects).

In addition, the user may control the explosion or implosion as a means of distraction or attack. The strength of these shards increase with through honing the mind.
