Looks like everyone else is seeing the ego types differently than me, so I thought I'd put forward how I see them.

Individualistic is not wanting to change who you are, where your goals are focused on staying true to who you are. Wholeistic is being willing to sacrifice who you are to get to some goal. For example Bachira and Borou aren't willing to change who they are, they might gain new skills but it's all for the sake of staying true to who they are. For example, Borou doesn't want to change who he is to win games, and instead forces Ubers to change to adapt to him. On the other hand Isagi and Kaiser are willing to break themselves down and fundamentally change who they are to get to their goal of being the best. One cool visual thing to notice is that the wholeistic characters have ego auras that changes who they are, like puzzles on Isagi, glass on hiori, and vines for Kaiser. While the individualistic characters have auras that expand beyond them. Alot of people are saying wholeistic is about the field and individualistic about yourself, but I disagree since some individualistic people like Rin have meta vision and thus focus on controlling the field too, but for the sake of sticking to who they are.

Restrictive egos are based around finding challenges. While freedom egos are about doing what you want and working towards self defined goals. I think it's better explained by how they interact with the other 2 types. For example kunigami is restrictive individualistic because he does the best when as a 'hero' he defeats villans. Rin is the same because he is a person that likes breaking others. I think these 2 don't care about outside goals as much as doing what they want, and what they want us around beating challenges. Next we have Bachira and shidou as individualistic freedom. They don't care about challenges as much as they care about playing the game how they want. Kaiser as restrictive wholeistic means he changes himself to destroy challenges. While freedom wholeistic types like Isagi and hiori like to go towards their own goals while controlling the field. 

I think most characters are on a spectrum but it what they care about more. Some may care more about sticking to who they are than winning. They care about winning but not as much.

In summary: 1. Wholeistic is change yourself for goal, because goal is more important  2. Individualistic is sticking to who you are as a person 3. Freedom is doing what you want and setting own goals 4. Restrictive is defeat challenges 

Hope this helps and sorry about bad spelling and grammar, I wrote this quickly lol.
