Daichi sometime can't fall asleep at night because he is insecure about his capabilities of being a great captain or not.

Everyone has seen his abilities of leading his team to success but sometimes he ponders what would happen if he spent more time with Kageyama and Hinata? Would they be different than the Duo we know of now? Maybe I should prepare little speeches before every match to inspire the players to do their best. Oh, Tanaka and Noya could quiet down more. They are going to be third years next year after all.

Thoughts like this keeps Daichi wide awake.

His lack of sleep can be seen the next morning at practice.
