A great headache came along with the sudden intervention in his mind. If described, it felt just like two enormous forces were clashing inside his head, trying to defend something while the other attacking it relentlessly as if wanting to open up the thing being defended.
It was like a part of him was getting forcefully separated from himself. It was painful, very much so.
"AGHHH" feeling the pain, he couldn't help but scream out loud.
If it was just physical pain, he wouldn't feel much. Nothing more than a mosquito bite as everything in his body was under his control. Even if it was soul pain, he would've brushed it off and just grit his teeth for some time.
However, it was an existence pain. By existence pain, this thing was endangering his existence. From the two forces clashing, he could feel that the traces he has left behind along with his memories were on the line of being erased.
