Curio
Disclaimer: Getbackers is drawn and written by Ayamine Rando and Aoki Yuya. I bow before their genius, and acknowledge that while a slew of other people have rights to the characters, I am not one of them. I do, however, own this story.
As the anime is all I've seen in its entirety, this story works in that universe's context. I may incorporate bits of manga canon as I read it, provided it doesn't contradict the show.
This story is already completed, but I'll be posting it as I polish, so updates may be irregular. Additionally, this takes place after the anime ends, so spoilers abound.
Prologue
It begins so subtly that Ban will not be able to say, later, when exactly it starts.
He does notice the man almost immediately, though he will never know it. Out of his peripherals, as they buy lunch at a stand (pizza, because if fetching lost pets is below Ban's dignity, it does pay, and Ginji couldn't have turned that granny down anyway). If a person staring at them isn't necessarily strange (they are both fine, fine specimens of male anatomy after all, and Ban doesn't mind if the girls just can't help themselves), it is unwelcome attention from a middle-aged businessman in a suit.
Not that that is entirely unusual either, but Ban can't help what Ginji's static does to his hair, and Ginji… isn't even inconspicuous unconscious. The man's perusal doesn't elicit more than the usual spike of paranoia.
Ban turns to glare at him anyway, and is somewhat disturbed to find the man has already melted into the park's crowds.
Habitual suspicion doesn't quite fade into the background, and a split second's distraction nearly costs him his lunch. It could have been a client, Ban tells himself, trying to eat half a pizza and step on Ginji's face at the same time. They'd handed out fliers earlier in the day.
Ban doesn't allow himself to believe this theory. He trusts his instincts, and they're clamoring to inform him that the man deserved at least a glare. Possibly a jagan enhanced one.
He's not surprised when, a block away and fifteen minutes later, Ginji throws an arm around his shoulders – a grin on his face – and cheerfully tells him they're being followed.
