With both negation superpower and Movement Petrification (Gold) that prevented him from both movement and escape methods, Takahashi Ken was very disgusted by Alister's ability.
He even started to doubt whether Alister was the tenth hero.
'Did the kingdom secretly summon the tenth hero and didn't tell the rest of the heroes about it? Otherwise, why did this guy make trouble with me?'
'The spirit realm can't be accessed by just anyone and even if they could access it, how would they know that the spirit realm was already conquered by me?'
When Takahashi Ken thought about it, he became warier of Alister's existence.
It was like an anomaly in this world. Takahashi Ken had never expected that someone like Alister would ever exist in Fantasia.
