(Only Dabi knows about Amisho cosplaying, no one else knows she does it yet) 

Amisho: Oi boss, I'm going to be out of town for a few days 

Shigaraki: What? Why? 

Amisho: Just something I need to take care of. 

Shigaraki: Well, it's going to have to wait because I was hoping you could watch over the LoV

Amisho: Why? 

Shigaraki: I'm going to the Anime Convention that's out of town 

Amisho: ...You are? 

Shigaraki: *eyes light up* Yes! I'm not usually a fan of conventions, but one of my favorite cosplayers is going to be there! *shows a video* 

Amisho: *eyes widen, realizing it's her* O...oh? 

Shigaraki: There's just something about her...she's so cute and adorable, but no one knows her real name, heheh...I must meet her...

Amisho: *clears her throat* Well, Dabi can stay and-

Dabi: Nahh, I want to see this cosplayer as well *grins at Amisho* 

Amisho: *growls* Well...I can't stay...

Shigaraki: Well, who else can we trust to watch over the rest of our team? 

Amisho: You don't think Spinner and Mr. Compress can handle Twice and Toga? 

Shigaraki: ...Hm...I guess you have a point, plus Kurogiri can keep an eye on them...alright then, I'll tell you how it went *goes to pack his bag* 

Dabi: So, how are you gonna explain this? 

Amisho: Shut up...he won't know...

Few days later at the Anime Convention

Shigaraki: Where is she? I must find her! 

Dabi: Is that her? *points to Amisho in a cute anime cosplay* 

Amisho: *talking to another cosplayer* 

Shigaraki: It's her! I can't believe I'm going to meet THE AmyCosplays! 

Dabi: Heh, this'll be rich... 

Shigaraki: *goes up to her* 

Amisho: *looks at Shigaraki, gulping but putting a smile on and making her voice a higher pitch* Hiya! 

Shigaraki: Um... *becomes shy* I uh...I'm a big fan...you're so cute and...Um...

Amisho: Hehe! Thank you! Would you like an autograph? 

Shigaraki: Um...I a-actually want a picture...please...

Amisho: *thinking* ['Of course he does...'] Sure! 

Shigaraki: *blushes* T-thank you...! *gets his phone out, taking a picture* I'll cherish this, thank you, AmyCosplays

Amisho: No problem! 

Shigaraki: *walks away, feeling happy and giddy* 

Dabi: *looks at Amisho* 

Amisho: *normal voice to Dabi* See? I told you 

Dabi: You really think he's going to stop at a picture? 

Amisho: ...Shit, he's going to try and kidnap me, isn't he...? 

Dabi: Probably, have fun

Amisho: *sighs* This is going to be interesting...
