Jayden's email

After the explosion in the IPMA building, Jayden goes to email Valentina to get information from her, then we see this:

"Seriously, talk about super sexy! I wanna support those love-packed Walls of Peace on your chest, Big Sis! How'd you like that explosion? Can't wait to hear back from you!"

This is completely bizarre for many reasons, obviously saying 'how'd you like that explosion' in the email, right after an explosion at the IPMA building that killed over 200 people. Why is Keropoyo reading out Jayden's email drafts to everyone in the room instead of just him and what is this email even in response to.

The scene comes out of nowhere and it completely changes the tone of the scene after we found out about the explosion with a joke from meow then it's completely glossed over.

The question is why would Ryukishi who always does things very intentionally, point this out to us in such a awkward way. It seems to be implying that Jayden in some way conspired together with the LATO girls to set off the explosives, it's also mentioned that he has been emailing with then ever since the battle standard festival.

The possibility of LATO being the culprit comes up and Jayden quickly deflects it

'If I were them, I'd never try an assassination this flashy in a place where they'd naturally be suspected!'

When Jayden and Miyao fight together, Jayden often makes mistakes and pointless moves on purpose, hoping that Miyao will notice them and point them out in his lectures, which he secretly likes.

"Now, when I screw up in practice, I think, yeah, Miyao's definitely gonna call me out on this one...and yep, he did! Sometimes, I'm almost looking forward to it. Hahahah, I must be crazy." - Jayden

So making such a stupid mistake like revealing his secret email to the entire chatroom with the word 'explosion' in it...

"Or could it be...they’re just looking for attention...so they’re showing off these openings...like some pre-teen girl?"
