Yui's gives him an excuse for having a helper in the other three games.
I don't even recall any importance to the Silica one. Probably some bullshit to do with friendship.
They all end up marrying him anyway after the end of Alicization anyway. Unless the story that happens in ends up being canned.
Now back to waiting for UTW so I can add more things to ***** about on this adaptation.
Has the next episode been confirmed for Warmth of the Heart yet?
Side stories are more OVA material imo. At this pace they'll end the season at the finish of the Aincrad story or rush the crap out of the ALO arc.
