Most of these can be up to your discretion whether you would like to alter the physical capabilities of your character to something more realistic or completely sealing their ability in the first place. Ultimately, please keep in mind that Inaba is a small town, real world type setting, so these abilities would need to be nerfed to the point where they resemble real tennis players. Anything impossible in the real world would need to be altered or sealed entirely. From what you describe, Inazuma Eleven's soccer moves would need to be sealed.

If you can come up with a way to make the impossible moves possible through altering, then your character may keep those altered moves. Everything else, however, would be taken. If it seems like it would be impossible in real life, then your best bet is to reduce the capability until it's shown as something more realistic.

As for the State of Self-Actualization, that will be sealed. Of course, your character may attempt to tap into it through hours of meditation, but the effectiveness of that means may not prove fruitful.
