War in Subterranean World: On top of Aranhgrad

Souta gave Airi his red-grade robe. It was to boost her overall stats so that she could run faster. He could carry them with his gravity power and blood but their bodies were too fragile.

Plus, the urges he was feeling were getting hard to control. There's a chance that they would die if he used his ability.

'I don't even know why I'm doing this.' Souta smiled wryly. 'Maybe because I subconsciously absorb the soul of their parents. That's why I'm trying to help them. I'm a hypocrite, isn't it?'

'Yeah, in this world... It's hard to survive without having a cruel side. Everyone had a side like that in their hearts.' Saya said to him. 'Even I once killed innocent people before. The people that I killed are probably higher than yours so don't worry.'

'You say that. Even so, I'm going to keep forward. I know for sure that I will kill a lot more in the future so I have to steel my heart.' Souta said to her with a smile.
