It has been several days since emthat/em happened.
Everything had been normal since then, as normal as it gets when you're a yakuza living in Ikebukuro where urban legends are walking on the streets as any other humans.
Akabayashi had been observing Shiki's behaviour. He was convinced something happened while he was staying over at that informant's place and he wanted to know what.
Yet Shiki acted just as usual. Still as serious, stern and good looking as ever.
The red head sighed, he was just imagining things, the only thing that changed since then was him.
Somehow, seeing his friend young again brought back high school memories, especially of the nights they spent together and he found himself longing for these nights, or rather said his body longed for these nights, not that he would mind.
Tonight, he had practically begged for Shiki to come over at his place again, swearing nothing weird would happen this time, that he just wanted to drink with him, making up for the last time when they couldn't.
After several attempts he finally convinced him to come and they made their way to the redhead appartment, which, since last time, has been miraculously kept clean.
Nothing else had changed since then, even the bottle full of this strange lliquid which transformed him into a teenager was still standing in a corner of the room.
"Akabayashi, why is this bottle still there?"
The redhead shrugged,
"Dunno, thought it was a shame to throw it, was thinking that since we know how to undo the effects we could use it against someone"
Shiki smiled softly,
"Oh, like whom?"
"That informant would be wonderful for a start"
"He's already a brat, wouldn't be much change"
As they were talking, they had downed several glasses of sake already.
Suddenly Akabayashi stood up,
"I need to go to the toilets"
Shiki nodded and smirked, when the redhead was out of his sight he stood up, took the strange bottle and poured a few drops in Akabayashi's glass.
The first thing he did when he came back was to empty his glass, going to the kitchen to fetch another bottle of sake, realizing something was wrong he stopped midway and turned back to Shiki.
His friend was wildly grinning.
"Shiki, you didn't, did you?"
"I did"
"But why?"
And then he stood up and walked, stopping right in front of Akabayashi he leaned down to whisper at his ear,
"Payback"
