Nyx's strength

Gasper suggested another possibility.

“I-It might also be an effect of not using Dragon Deification.”

Yes, I could transform even further. Though I did get the power that let me fight against God-class beings, I decided to use it only in important times as it really made me tired. Well, I guess it wouldn’t work with this crimson armor as the enemy was the primordial Goddess of Night, Nyx. If an all-out fight did break out, I would have to use that form. However, Nyx denied what Gasper had just said.

[Fufufu, that’s not it. I just came up with a strategy against Oppai Dragon.]
