Takaoka and Nagisa were facing off so they would make Takaoka leave. when it ended, he had Takaoka on his knees, absolutely defeated physically but mostly mentally. Takaoka was terrified since he saw nagisa as a vicious python, so did Koro sensei and Karasuma, that's why Nagisa was chosen. you've been hurt already like Kanzaki and Maehera except bleeding. karma was holding you in his lap, putting a bandage over your forehead where you were bleeding, Takaoka left

karma: you doing ok?
