So, fair warning, this sorta delves into spoilers. Kind of. It's more of a funny background event than anything, but it does have context in the story.

That being said, Makoto following Akira around is some silly, funny shenanigans.

Akira strolled out of Untouchable, his wallet slightly fatter from the bits and pieces of treasure he had borrowed from Palaces. He adjusted his school bag, wandering out onto the street when he caught someone wearing a similar uniform. Morgana popped out, cocking his head quizzically as Akira looked at the book covering her face. "...Isn't that the student council president?"

"Yep."

"Is she following us?"

"Uh-huh."

"...Are you gonna mess with her again?"

Akira lowered his head and smiled, reaching up to scratch the cat's ears. "Maybe a little."

Morgana ducked back into the bag as Akira headed into the street, purposefully wandering to every establishment he usually frequented and checking to see if Niijima was following him. Predictably, she was, sneaking looks at him from behind the cover of whatever she was reading. Akira guessed it was a sort of manga. He toured the central street of Shibuya for a while, walking into stores and sometimes buying something that looked particularly useful. What is he doing…?

Makoto watched Akira step into an alley, quickly following him while keeping the book firmly in front of her face. He must be going to the scene of the crime…!

She swept into the alleyway, only to find that it was both a dead end and that Akira was nowhere to be found. "What the-"

"Niijima-senpai."

Makoto yelped and dropped the book, jumping away from Akira. Somehow, he had appeared behind her, wearing an amused smile before shifting to a more neutral expression. "Isn't it a bit dangerous to be running around and reading at the same time?"

"I, er...well, yes, but-"

Akira ducked down to pluck the book of the floor, and Makoto swore she saw bright blue eyes peeking at her from inside his bag. Yet another question that probably wouldn't be answered today. He gave the pages the briefest of scans before handing it back to her, a finger lodged in the page she had been stuck on for the past twenty minutes. He smiled softly, mirth gleaming in his eyes as he murmured, "Wouldn't want you to lose your page."

He bowed his head politely, walking past the stunned girl and towards the exit of the alley. "Also…"

Makoto turned to look at him again, the book just barely clutched in her hand as he shrugged and said, "That's an interesting choice of story you've got there. Not that I'm one to judge."

For a second, Akira grinned, eyes twinkling merrily that he had gotten away with it once again. "Everyone have secrets, after all."

He turned his back to her again and walked out of the alley, waving lazily over his shoulder as Makoto watched him go. After a moment, she sighed, idly looking at the cover of her book. Akira heard the squeak of shock echo throughout the alleyway, snickering to himself as Morgana purred happily in his bag. He got the feeling that wouldn't get old any time soon.
