Ramiris (Light Novel), for 5th spot in 10-C.
As starting move, Ramiris use her "Small World" ability she rewrites the coordinates of 3D beings and 4D universal space-time continuums, isolating them in the (2-B) labyrinth bounded by countless space-time continuums. Her "Small World" ability consists of information type 2, and her ability is based on influencing conceptual laws through 3 layer law manipulation.
In addition, as a Spiritual Lifeform, it does not die unless its soul, which is a type 2 information, is erased or its core, which is a type 1 concept, is destroyed.
However, Ramiris' ability is thought-based, so let's still see what the other side can do.
5.
SCP-239 (Ramiris resists all of her major abilities, the only ability she does not resist, existence erasure, does not appear to be at the information type 2 or type 1 concept level, so it is useless on Ramiris)
6.
Sōya Azashiro (Azashiro's passive reiatsu crush does not work on the soul of Ramiris which is information type 2 and his nigh-omnipreset won't work either, as Ramiris would directly isolate the universal space-time continuum)
7.
Floating Eye (Only notable ability, mind manipulation, is useless against Ramiris, who has a information type 2 mind and both unconventional resistance and mental invulnerability)
So she should at least beat these characters.
4.
Culaina (Speed Equalized) /
Chess Pieces (Speed Unequalized)
These two for need a matchup, there is a possibility of incon.
