The elder brother (the left one, sitting on the PC, his name is Anisha) likes to watch guro,
porn and other naughty stuff.
He is kind of stupid and often falls for browser crashing sites.
The younger brother's name is Otoutosha (Anisha & Otoutosha translate to "older brother"
and "younger brother"). He likes to make fun of his elder brother.

They often both do a kind of masochistic tsukkomi act which is difficult to translate.

I don't quite know how to translate their favorite phrase (流石, it also appears in their name) -
it could mean something along the lines of "saw that one coming" or "indeed" or "clever".
Maybe someone with a bit more knowledge of Japanese can help us out here.
