Liang (Obito), Mansui (Sasuke)
The apocalypse begins with a massive explosion.
A meteorite from beyond the world crashes into the capital...
An invisible, strange substance spreads outward from the blast site, reaching everyone in varying amounts...
The amount of this substance determines one's starting talent, but only a tiny fraction of people can awaken it.
For example, Mansui was farther away, so she grows stronger gradually. Liang was right at the center of the blast, so he started with the Three-Tomoe Sharingan.
A Mangekyo ability is determined by the emotions felt at the time.
Using it won't cause blindness, and it grants night vision, but it consumes stamina based on one's physical fitness.
For example, Mansui is exhausted after using it once, while Liang can use it repeatedly.
