It's not like the Otaku in Japan that take photo's of cosplayers give much mind to the skirt anyways. Except to maybe get their camera's lower so they can get the shots under it. Save them some time and neck problems girl.
Prediction: She's going to go out there without her skirt, and everyone is going to think she's re-enacting a post-battle scene where her skirt was destroyed.
LOL that sure played out as foreshadowed XD! Nice leading XD! It's great that it's not overly done too like they are missing each other and it was a glance. Now... if only Lilysa wasn't so easily swayed, thought she would be straightforward enough to be able to miss the entire intimidation since she's quite simple minded at times, but then that pressure from it being the 2nd time she attends a cosplay event... let's see where our MC stands in to support her and how Mayura-sama intervenes with the entire thing XD!
