I'm not really sure right now if it has a manga as well, but a novel that would be pretty similar would be Conquering Hero's Heroines.
In that, the MC also 'assumes' or is the role of a 'villain', who's a bit of an asshole ingame, and is later defeated by the Hero party.
But all the...

If it was real battle, they would be inside the mechas probably, and he therefore wouldn't be able to see it, unless he had already damaged their cockpit.
@Mojo
These types of stories generally have the 'heroine' either convincing, seducing or tricking any 'targets' onto her side.
As for the ink... if he wasn't the one who's responsible for that part, he probably revealed it and someone else did it.
@parkourse
They would.
Provided they also had a way of retrieving the items, which might be either magical items, water magic or enslaving aquatic beings.
@ac45king
Most of the hero association members to my knowledge were doing it to help people , to prove themselves or because the association offered them something good.

If he had the logo of a specific chinese restaurant on that bike, and the reporters noticed it ,that restaurant is going to get some weird calls sometime soon
@plastic_sludge
Assuming he's got a harem, do you actually think he realizes he's got a harem?
He would probably be like 'these girls are very nice and all, i'm lucky to be their friend and it's fun talking to them'

If there's an existing slave trading network / underground, then unless you eliminate everyone currently benefitting from it or atleast anyone capable of maintaining such a network, it will reform in due time
@Jake1456
If the hero is the MC's childhood friend in these types of novels, more than not they know of the Mc's powers, but don't reveal them / think them obvious to anyone else, but generally side with the MC.
@Vergift
Provided you've got people with the right kind of unconventional builds, you could probably make an entire party of such people.
Maybe a Tank with only aggroing and armor/health stats
A Mage with only AOE spells of various sizes & scales
A Priest with extreme amounts of mana, but only...
If they aren't together in those 10 years, the kid could probably get them all the paperwork necessary to marry, then get them drunk and sign it, thus making them legally married to eachother
