What I really like in the story is that he keeps doing good deeds, even though it's for another reason.

You regress and re-awaken as a young, orphaned angel with very little money. You were previously a non-awakened human in your 20s and it should be reasonable to think you had some life experience as you were one of the last to die at the hands of the demon kings forces.

Your world is a game-like world with stats and skills. You've been tasked with 'raising heroes to defeat the demon king'.

Even though you were previously a normal human with no practical understanding of how a hero academy operates beyond a past fascination with it and some obsessive internet surfing, you decide the best place to raise appropriate heroes is a nearby superhero academy that conveniently provides basic living necessities like accommodation and food... and is also conveniently the most famous in the world.

But your starting stats are woeful. You need to improve so that you can get into that local superhero academy via the upcoming entrance exam.

Shortly after reawakening you're thrown into a dangerous situation and obtain powerful healing abilities. For some reason you've also obtained the broken ability that when you do a large, meaningful angelic acts you can use excess angelic power rewarded from such acts to increase your stats. And luckily the broken ability is results-focussed and not entirely dependent on intent.

Due to your past life fascination and unvalidated public released info you recall, you decide you have to get in to the academy ASAP at the very beginning of the academic year (even though it's established from the get go that it'll be well over a decade before the world ends) and you can't delay to next year or find out if you can transfer in part way through the year... for some reason you can't imagine there's any other/better way to meet your goals or your basic living requirements and there's no reason for you to radically and quickly power up.

Do you:

- go somewhere where you can immediately do powerful angelic acts, get big rewards and rapidly increase your abilities to any level caps as well as leverage the goodwill you can obtain by doing so, so that you can continue to level up and to rank up (eg: any of the numerous hospitals or aged care facilities that are around or any of the better powerful guilds that's would welcome a powerful healer)... or any of the multitude of other things you could do that lean on your skills that would have the best payback for effort... and ensure you are a powerful force, so you can focus all your efforts on raising heroes once you enter that damned academy you think is the best route;

OR

- do you go to a BBQ restaurant run by a hidden elf examiner with martial arts skills that you think you can convince can get you in due to a past life documentary?

I'll give you one guess what our regressed, experienced MC chooses to do.

if I remember it correctly, he seems to be the archangel for justice
