well back when i was still in school the otaku are a bunch of creepy introverts but the senior members aren't. they have a rock band, drink a lot, smoke a lot and very enterprising. they bought naruto headbands and kakashi gloves by the bulk and sold them for 3 times the usual price.
I'm in good terms with them but i prefer not to hang out except during exhibits.
the 'otakus' in my school ,not that there are many, are either classed as goths/emos or freaks no one socailises with.. not me lucky! xD im reasonably popular becuase im a bit of a freak xD funny how that works you know ? but tbf they dont have a wide enough anime range to call themselves otakus in my opinion haha
