In their exchange, Seraph finally managed to wing Phune with a holy blast, leaving his arm numb, but with a frustrated snarl, Phune waved his other arm and hit Seraph in the leg with a sphere of water. Seraph collapsed, howling in pain as the water dissolved his clothes and flesh. He had felt this burning before, this corrosion of his skin. Noah had used acid against him during their fight, and right now, a tsunami of bad memories was washing over him. In his mind, he was back in the slums with Noah standing over him. Considering where the arena was built and where Noah was watching from, his delusion wasn’t far from reality. He couldn’t go through that pain again, that horror.

The fight continued in that fashion. Over and over again, Abner charged Reiss, only to be soundly beaten and hurled back. He’d hit the ground and slowly get to his feet, often while reciting some motivational quip that made Noah roll his eyes. The young man’s tenacity was admirable, but Noah wished he would stop screaming about the merits of determination and friendship. He had a rule against taking pleasure in the suffering of others, but was letting this fight continue for his amusement in seeing Abner getting knocked around. Even for an ancient spirit like Noah, the young man’s unrelenting “put me in, coach!” energy was aggravating, and he wanted to see his spirit break.

idk if you've played chaos;head (or watched it, I never saw it so idk if it's in the anime) but it's set in the same world as steins;gate (which I've watched but never played) and things the eyes see but the brain doesn't process are a literal plot point, you could almost certainly make a fairly lore accurate manip with that if you like this world.
