I was a completely run-of-the-mill otaku 
leading a completely ordinary life.
كنتُ أوتاكو طبيعيّاً تماماً يعيش
حياةً عاديّةً تماماً
Ich war also ein ganz normaler Otaku,
der ein ganz normales Leben führte.
Soy un otaku común y corriente.
Soy un otaku común y corriente.

che conduceva una vita ordinaria.
Eu era um otaku medíocre
vivendo uma vida comum.
Таким-то я и был раньше —
ничем не примечательным отаку...
