Birthday: December 25  Taishi, he is not A otaku, he is THE otaku.  A loud and very eager friend of the main character, he is very fond of fan comics and is the one to get the main character started with drawing fan comics. He is normally in a light brown suit, or his school uniform and a pair of orange glasses.  He is always talking about world conquest and how all the bad things that happen is a part of his great plan.  He is also the founder of "Brothers 2" the fan comic club which the main character is also a part of.

Destiny or delusion? It's a hilarious rollercoaster of laughter and confusion when Taishi, the ultimate otaku, drags his friend Kazuki into the swirling world of ambition, hatred, and love - the world of fan comics! Poor clueless Kazuki must sink or swim when he's dumped straight into the middle of a massive comic convention. Lost amidst hoards of buyers, sellers, and cosplayers, Kazuki is about to be baptized by fire, all in order to lead him toward his true calling: to take over the world through fan comics! 
Meanwhile, Kazuki's childhood friend Mizuki isn't about to let him be dragged from his normal life without a fight! But will she be able to stop the addictive draw of the new world that lies before Kazuki? Little by little, Kazuki is slipping down the path towards destiny - and Taishi is shoving him every step of the way!
