A world much more wonderful than the one you lived in!

It's just a little awkward. You'll get used to it soon!
You all must have had to leave for somewhere to begin something. To the office if you were a worker, to school if you were a minor, or into guilt toward someone if you belonged nowhere.
But were those all things you wanted to do? Weren't you forcing yourself to continue them just to prolong a miserable life, or because you didn't want to fail someone's expectations, or through a minimum of conscience!
O Peter Pan, who is in unrequited love with childhood, you don't have to run that treadmill here. You don't have to embrace and keep those muddy things. You shall act according to your instincts and desires, and simply play.
Because that is Tsukasa's w o n d e r!
When you open your eyes, you are in a playground somewhere. It is definitely a place you've never seen before, yet it feels somewhat nostalgic.
You look around. In the distance, countless houses are lined up. The sky is clear. Rainbows hang here and there.
What is placed before you is a warm lunch box, a very wide-looking playground, and a tall man.
—Welcome to w o n d e r!
Wonder?
Self-introduction and guidance!
My name is Tenma Tsukasa! I am five years old. I am a child just like thou!
Haha, welcome to w o n d e r. This is a very, very wonderful place. It wouldn't be an exaggeration to say it's the happiest place in the world. At least, that's what I think.
Here, there is no need to worry about anything. Thou need not think about work, money, responsibility, or tomorrow. Thou simply need to eat, sleep, play, and laugh. Happiness is childhood, and children are beings who live that way by nature.
So thou no longer need to pretend to be an adult.
