At this moment, you were smushed in between two nervous anime lovers that you call your boyfriends. It's pretty weird... Dating the son of Hades and the Avatar of Envy. Meanwhile your just a human... An immortal one!! You never thought that you'd meet a demon or a magical being in the human realm, but you did... And here you are, with Idia napping on you (his head is on your lap) and Leviathan watching anime with you in HIS lap. Leviathan was watching Ruri-chan's anime yet again, and he actually got Idia a bit hooked onto it too! You personally would rather Madoka a bit, but you'd never tell them that. He kept silently cheering Ruri-chan on, as Idia kept sleeping on you. Leviathan made sure not to wake Idia with his soft cheers of amazement.

Leviathan: "Yeeeaaahhh!! This is that time she beats all the bad guys with JUST her shovel's power!!"

Leviathan cares deeply for you and Idia, same with Idia when it comes to you and Leviathan. So that's the reason why he being quiet.
