I've had this chapter for months and frankly I just need to move on with the story so here it is! Honestly it could be a lot better but I have Plot Ideas that I want to get to and if I deliberated over this chapter any longer it would take many more months before I posted it.

Believe it or not this chapter does set up some important stuff that'll come up again at the USJ! I'm super excited to write it.

If you didn't see the last chapter's edit, Katsuki is no longer experiencing female puberty and all the blood that entails. I was thinking of it like "In an ideal world, wouldn't I like to fully transition at a young age and have fully functioning reproductive organs?" but from a readers standpoint, when I went over it again it came out like "The author skipped over details to assure you that his character is No Longer Trans." Thanks for commenters for pointing this out, it did take me a while to change it but it definitely makes for a more relatable experience for readers.

"Kacchan?"

"Yeah?"

"Why are you wearing a ninja costume?"

Katsuki hadn't intended to be caught, but she could always use a co-conspirator.

She squinted at Izuku. "Zucchini. Wear the darkest clothes you have and follow me." She paused. "Get rid of your boots."

Izuku squinted back. "Kacchan, we're fifteen minutes away from my house. Why would I have a spare change of clothes with me at six in the morning?"

That was a valid point. Most people didn't carry their entire wardrobe with them. Maybe Katsuki was more feverish than she had thought?

She noticed for the first time that Izuku was carrying grocery bags.

"...Huh." She laughed.

He was definitely staring at her in concern, and wow! Look at the time!

"Gotta go, see ya Cucumber!"

She made a break for it.

5 Days Before The Incident

Katsuki had been walking back from a costume shop in an area of the city she didn't usually visit, when she spotted him.

Purple hair. Eyebags.

She couldn't be one hundred percent sure, but boy did he look like a certain future general studies student.

...It would probably be rude to approach him, right?

Before she could decide on what to do, Possibly-Shinsou had disappeared into the crowd.

In her old world, a purple haired child would have had a very difficult time doing that. Now, what with the furries and such, it was not so.

It made her want to dye her hair, if she was being honest.

Katsuki only noticed she had been standing in the middle of the street when a nice old lady with feathers instead of hair asked if she was alright.

Getting away from the lady as politely as she was able took longer than Katsuki had wanted. She didn't want anyone remembering she'd been in this part of the city in the event that her plan went south.

Katsuki was supposed to be in bed, suffering from a fever. She was still doing half of that, and if she had her way would be back home before anyone noticed she had replaced herself with a sleeping bag stuffed with pillows.

She probably shouldn't be up, but she was going stir-crazy staring at the ceiling. She couldn't even see Izuku!

All she needed to do was find the train station.

4 Days Before The Incident

Katsuki didn't usually get sick, but when she did it was bad.

She was practically a walking explosive, every little sneeze or cough setting off her hands.

She'd already gone through five pairs of fire retardant gloves!

After her successful sneak-out, it got even worse.
Could a girl not buy a ninja costume in peace?

Evidentially not, because every time she tried to use her phone her nose would twitch and she'd end up flinging it away from her to save it.

After many near-misses and subsequent cracks she gave it up as a lost cause. She wasn't willing to wear oven gloves just to play this worlds equivalent of neko atsume. (It was called koneko atsume, and it was glorious.)

Katsuki had already looked up the information she needed for her plan days ago. All she needed to do now was wait.

3.5 Days Before The Incident

"Katsuki? Do you need anything?" Her dad peered through the gap in the door.

"Can I borrow your thumbs? I wanna play animal forest."

He ended up buying her a phone stylus.

Day of The Incident

It turned out vandalizing a hero agency while wearing really conspicuous clothing wasn't a great idea. Katsuki had managed to write 'Fu' in blaring red, but before she could work on the 'ck Endeavor' she was bodily picked up and carted to the police station by a hero sidekick.

She had a feeling that she wasn't the first one to try defacing it.

Which led to her parents talking with the police.

Which led to her explaining her side of things to the police.

Katsuki was pretty certain she was supposed to ask for a lawyer, but at this point it was obvious enough that she'd done it.

"I was writing 'Full of Hope, Endeavor'." The police officer looked nonplussed.

Katsuki tried again.

"You see, Endeavor is such a role-model to me, I just had to let him know. He doesn't give out autographs often and I've never had the chance to meet him so..."

Her parents were looking at her. Katsuki was studiously looking at her thumbs.

She might have been feverish, but she had looked up the legalities of vandalism before she decided to go through with it. As far as the police were concerned, as long as a quirk wasn't being used it likely wouldn't go into her record.

Katsuki had been purposely acting as out of it as possible to give herself an excuse, should she need one.

Admittedly, if they did look into it and saw that the ninja costume was a recent purchase she could get into a lot more trouble. Premeditation, and all that.

Luckily, her parents seemed far more concerned than angry at the "out of character" behavior.

Unluckily, that meant a whole lot more bedrest and disappointed text messages from Izuku, who disapproved of her 'self destructive behavior', and how she 'knowingly and purposely set herself up against authority figures for no reason other than to get one over them'.

He had a point. Katsuki was...not all that fond of herself.
She couldn't stop pushing boundaries, and it was getting to the point were she was doing illegal stuff just to spite...something. She wasn't even sure what she was angry at.

She saw life as a game, and had a hard time seeing people as anything other than NPCs.
Trouble didn't seem real to her.
She had only a loose idea of what she wanted.

Katsuki owed it to her parents and Izuku to get better.
