Edith happily sits at her desk. Hearing Jerome speak Edith looks to the board, trying to absorb the words coming from her teachers mouth. Something about personalities and costumes? Come to think of it, something was mentioned about needing a costume, Edith had just kinda forgotten about it.
Edith racks her brains for information on costumes. Heroes wear them and so do villains, her parents had costumes. After thinking for a minute Edith remembers a conversation on the matter she'd had with her farther had told her a long time ago.
'A costume should be intimidating and imposing, fear is as much a weapon as any quirk. That said, it doesn't need to be elaborate or all over the place, then you'll just end up looking like a dickhead.'
Her father costume had been a two piece suit with a few creative and rather sharp looking flourishes. Thinking on it Edith decides that a suit would be too uncomfortable, but that her uniform is comfortable enough. Drawing a picture of her uniform albeit plainer Edith goes back to thinking about her fathers advice.
'The most important thing in a costume, even more than intimidation, is function. Take the spikes hidden in my suit for example, a hero pricks themselves on the wrong part of my suit and the next thing they know their on the floor with their blood boiling inside them. I can tell you that ones saved me more than a few times.'
Edith wouldn't really be able to benefit from spikes in the same way her father did, her powers needed more than a prick to be effective, sitting their for a while Edith remembers the tanks her mother used to have within her costume for storing water she could manipulate in a fight. After wrighting down 'water bottles in suit for blood', Edith takes a look at her handy work. The lines are all janky and the entire work is barely above stick figure level, but the concept is translated okay enough.
After that Edith hurriedly writes down a brief and rather poorly worded description of her quirk, before running up and holding it out to the teacher proudly.
"Did it!"
