although there's no set rules where you have to open the other 2 doors to get to final TnK,
i'd think that it would be easier if you had the doors open first and be one step away, rather than have that fun tennis attitude,
and not opened any doors.
a little kid age 12 who loves playing tennis could theoretically get TnK vs other pot players that dont have it?
just opinion of course.
The problem is that opening even one door generally takes you very far away from the 'have fun' attitude. For example, we know Chitose opened his door by attaching random machines to read his brain waves and push himself to the limit. Obviously that's not having fun. It's unclear how Tezuka opened his door but he's also about as far away from 'have fun' as it gets. Ryoma might've had fun opening his two doors, so you get 1/3 had fun opening the first doors while 2/3 did not in the limited sample.
Given the explanation, my guess is that TnK is not meant to be invinicible, so a beginner with TnK will still get spanked by any decent POT middle schooler, for example. Nanjirou specifically said that people forgot the feeling where you enjoyed tennis even while getting spanked. Given the way POT works, it probably goes like this:
You start playing tennis in TnK.
Since everyone around you is some kind of superhuman you still get spanked.
So you decide to get better at tennis by learning from someone better than you or join a club, and yet it's clear that most tennis clubs in POT are really death march camps. Even Ryoma, who learned TMnK, resented having to run a marathon to replace his strings (Inui picked an especially far away shop to build his endurance).
You attempt to model your style after some known good player:
A. Power player - Your life involves trying to maim someone and you're likely to get maimed too. That's probably not very fun.
B. Tezuka - His powerful moves are all self-multilation moves, probably not very fun.
C. Sanada/Yukimura - Their whole philosophy is around winning at all costs.
D. Atobe - Another guy doing whatever it takes to win. He changed his style simply because he believe it's more effective at winning.
E. Shiraishi - He said that Bible Tennis is very boring but winning comes first, so no go there.
F. Fuji - Fuji lacks motivation to play seriously against weak players. Unlike others he at least has fun playing the good players, but he's always shown to be disinterested against weaker opponents, so he hasn't totally grasped the fun part.
Almost everyone you'd use for a role model is almost certainly to take you very far from 'have fun' so you'd never get back to TnK again. Fuji is about the only guy who can even get you halfway on the right track.
So I can see why nobody would ever think 'have fun' is the key in the world of POT. Drinking Inui's special drinks alone should be able to suck all the fun out of someone.
) then nobody will get it.
