Upon pressing the Add Button Ryutaro would be prompted to give the person's name that he wanted to add, having to speak it out loud since it didn't seem like the strange <Gamer> ability was going to give him a keyboard as of yet. The exact window saying: 

[hider=Window]
Who would you like to Add?
[/hider]

Upon giving Sasha's full name, either muttering or speaking it out loud, whichever he preferred, a window would appear in front of Sasha now. 

[hider=Window]
<Ryutaro Eikichi> has sent you a Friend Request. 

<Accept (Y)> <Decline (N)>
[/hider]

If she would choose to accept her own Friend List would appear in front of her now showing Ryutaro's full name in it along with a small green circle right next to it. If she declined, the window would simply disappear and nothing else would happen. If Sasha did accept then Ryutaro's own Friend List would be immediately updated, showing Sasha's full name as well as a small green circle next to the name. It was unclear as to what the circle's meant, but it would now be possible, not that either of them had tested it yet, to maybe send messages to each other since a <Message> button was present.
