Heaven is pretty great!
It's basically like staying in a luxury resort. Every day I sleep in and get awoken by a beautiful angel maid then eat a sumptuous breakfast.
I can order basically anything to eat and the chef will even create new foods for me. Kageyama ate things that didn't exist in the world I used to live in. There was meats and spices that he had never seen before.
It was quite a good life.
If it weren't for that pesky Gabriel
Every time Kageyama wanted to relax or do anything Gabriel would be watching him. It really ruined the mood considering the fact his dead eyes would bore holes through Kageyama's (fake) body.
It was rather annoying.
Apparently, Gabriel was Kageyama's "afterlife manager"
Although Gabriel didn't seem to do much managing and mostly just kept an eye on Kageyama.
It was still annoying.
The few times Kageyama tried to speak to Gabriel he was brushed off and ignored.
Gabriel seemed to find Kageyama's existence troublesome and would avoid him.
Even when Kageyama called for him Gabriel would resolve the issue as quickly as possible and leave.
It was indeed a very weird relationship. Despite this Kageyama still enjoyed his happy afterlife.
He spent a lot of time catching up on all the Manga and Anime that he missed. There wasn't any real conception of time and thus Kageyama could enjoy every single creative pursuit ever created by humans. On the other hand, it also meant that if anything was cancelled and never continued Kageyama would still be out of luck. He was shocked to find that quite a few of the Anime's he liked never got a second season.
[Curse these studios!]
Unfortunately, even with his vast wealth Kageyama still didn't have the ability to make more seasons on his own.
Still, he enjoyed his (after)life. Even if some anime were canceled he spent many long hours cooped up inside his hotel-like room simply watching anime all day.
He could also play any video game he wanted. Only single-player games though! This greatly
saddened Kageyama since he was quite fond of MMO games.
Kageyama even had a personal maid. Her name was Maxine and apparently, she was an angel as well. Unfortunately, Kageyama learned very quickly she was not the "ecchi" kind of maid and a regular old maid. This was a shame and a little bit of a disappointment since Maxine was quite cute. Not beautiful, but she had a girl next door feel that make Kageyama very fond of her.
Every time he asked her to do something she would bow and say
"yes master"
She seemed able to do nearly everything. From playing board games to sewing, and even setting tables.
Kageyama felt like a wealthy playboy and had quite a lot of fun in the afterlife
thus Kageyama spent nearly 1,000 years doing just that.
