Up to the extent of Kishirika's knowledge, he knows everything he sets his eyes on.
From now on, even if a similar situation was to happen, he can handle it on his own.
Cliff is taking it like a man.
That man currently, unable to control his Demon Eye, is struggling along.
Everything in the world with name and explanations attached.
A world covered in words.
Even now he cannot walk about without Elinalise guiding him.
But he'll learn to control it eventually, after all, Cliff is a genius.
Until then, he should wear an eye patch.
