This could be the most asocial thread ever, just warning you. :(
[The arcade is hardly among Anri's favourite spots. Too noisy when she needs absolutely no help hearing extra noise, often crowded with people -- not to mention her being rather terrible at video games. She passes by the exterior, less than a second taken to eye the glass windows and ensure that her reflection shows only her, but halting when she sees Touma.
Guilt is a bit foreign but seeing his cast and sling does give her pause. Checking up on him after an injury - that's what people do, right?
She pushes through the doors, waving a little. Say hi, Anri!]
