Chapter 4 idea:

Saya and Katana (real names unknown): These twin girls were turned against their will in irregulars, they used to be shy until they turned into fun loving girls who just enjoy causing problems in everywhere. They like each other, both are fast fighters in their own. Katana uses fire and Katana earth, they form Magma powers.
