I saw the first page and though: "Yeah! I knew Nagisa had it! As someone who also slept through classes and aced the tests I can guarantee he's one of the best and school is just boring to him."
Then I saw the ice magic and though: "if he was already my favorite character, he's even more now, and with that chaotic incantantion too... if I had to write a character to play DnD in this world setting, I'd be him."
Then I saw the following pannels... well scrap the first part
. Still my favorite though, from activation phrase, to ice magic, to sleepyhead.
