...Ignore this. I completely forgot.
The Original Kamukura Izuru (the school's headmaster, picrel)'s name is written in hard Kanji, meaning especially troublesome moon runes while Kamukura Izuru (beautiful alterego of the hajimeme)'s name is written in simple Katakana, similar to the rest of his classmates and Hajimeme himself. My bad, I was too caught up in a chance to call Hajime stupid.

He doesn't, which I literally answered already...
Komaeda literally babysits him 24/7 never leaves his side in the investigations so he would pinpoint all areas of interest and useful evidence and then goes on to explain their purpose and meaning in the class trials. Chiaki picks up babysitting duty when Komaeda is away and does the same thing in trials, except she's much more honest and helpful so she speaks pretty frequently and gives Hajime all the points he needs to connect.
The real brainlet... Is Kodaka himself.
