Another possibility is that the kid is being controlled or influenced in some way. It could be by a dark power that has taken over their mind, making them attack with the sword against their will. Or maybe they are under the influence of a powerful spell that forces them to fight in a tournament or something similar in the visual novel's world.
Well, it could be that the kid is in a fantasy world where they have to fight for survival. Maybe their village was attacked and they picked up a sword to defend it.
The visual novel might show the kid with a determined look on their face, gripping the sword tightly. There could be a lot of motion lines around the sword to show the force of the attack.
Another visual novel could be 'Kid's Quest with Wooden Sword'. It's set in a medieval - like world where the kid, armed with his trusty wooden sword, goes on a quest to find a magical artifact. Along the way, he meets different characters, some friendly and some not so much, and has to use his wits and sword - fighting skills to progress in the story.
I'm not sure specifically as I haven't read this particular visual novel. But it might be about a kid's adventure where the wooden sword is a key element, perhaps in a fight against some sort of evil or in a quest for something important.
The art style is crucial. Using detailed and expressive character designs for the kid and the action of swinging the wooden sword can bring the theme to life. For example, showing the determination on the kid's face as he attacks.
Since I haven't read it, I can't say for sure. But likely, the kid with the wooden sword is a main character. There might also be a mentor figure who teaches the kid how to use the sword better.
A big kid might need a diaper if they are on a long - flight. For example, a 10 - year - old with a weak bladder. During the flight, the diaper gives them the freedom to move around, watch movies, and not worry about finding the restroom every few minutes.
A Skull Kid might meet a gentle forest spirit. They could bond over their shared love for the moonlight. Every night, they would meet at a special glade where the moonlight shone the brightest. The Skull Kid would make little sculptures out of moonlit moss for the spirit. Their love was quiet and serene, like the stillness of the forest at night.
Some may create a 'homeless kid fake story' to gain attention. They want others to think they are kind - hearted or to make themselves look important in the eyes of others.
One possible reason could be mind control. Maybe an enemy uses a powerful genjutsu on Naruto, making him lose control and attack the villagers. For example, Orochimaru might have a new jutsu to manipulate Naruto's mind for his own evil purposes.
Maybe it was just pure curiosity. Kids are known for being curious about things and the onion might have looked interesting to him.
