I hate Japan for making depressed and brooding characters seem so cool. It pains me because I want to be this dude, but he's based on Osamu Dazai, and I would NEVER in my life want to experience that pain.
I love this already. An explanation of the Truck. Uninterested MC. And the summoner knowing the personalities of the Heroes and having prepared lines for them. I LOLed when one of the heroes picked up the sword and she showered him with praise and she prepared to show MC his superpowers to change his mind. Because we all know that's all most heroes care about.
