Initial D First Stage, Tonari no Seki-kun Recommendations
Well, this is my first recommendation.
And why I recommend this anime, even I don't know. Initial D is similar to Tonari no Seki-kun because of Takumi and Seki.
I can't help it, but whenever I see Seki-kun, I see Takumi doing all sorts of crazy things in the classroom. When Takumi is spaced out he actually is doing what Seki-kun REALLY does on his desk!
They both don't talk often, and make the same faces (Takumi spaced out, Seki-kun 'Killing Time' face). Both don't like losing.
Also, Yokoi reminds me of Itsuki, they always look up to Seki(Takumi) and speak most of the time.
