they're step brothers? for some reason, i thought they were cousins or something haha
i thought so xD
at the update Chapter 22 Kaname said if Shino maybe related with Riou, and Riou just silent so Kaname left shocked like "Oh.. i see." xD
From what I gathered from both manga and anime... They might be brothers or else somehow connected by the past events...
They are brothers from the same mother i think
They're brothers. You should watch the anime. It clarifies it there, or I suppose it's evident, and is farther into the events than the manga.
they are step brother, right?
╮(￣▽￣)╭ that's why Riou very protective over Shino?
