In manga girl tekking, the style often emphasizes cute or fierce looks for the girls. The technique could involve shading to add depth and using special effects for movement. Also, the background might be simplified to focus on the girl character.
I'm not sure specifically what the 'Tekking 101 Manga Girl Story' is about as there isn't much information given just from this title. It could be a story about a girl in a manga that has some unique elements related to 'Tekking 101', perhaps a story about a girl who is into tekken - like fighting in a manga world.
In fanfics, Admiral Kizaru's power can be highly exaggerated. His Pika Pika no Mi ability, which allows him to move at the speed of light, can be made even more potent. Writers might make him capable of creating stronger light - based attacks or having better control over his speed. For example, he could be shown to split into multiple light - clones more easily and use them in more complex battle strategies.
Another theme is loyalty. Kizaru is often part of a group, and fanfictions explore his loyalty to his comrades. There could be stories where he has to choose between following orders and doing what he believes is right for his friends. This creates interesting moral dilemmas within the story.
Since the title implies a girl is central to the story, she's definitely a main character. There could be other characters like a mentor figure who guides her in the Tekking 101 world. Maybe there are some opponents she has to face in the story. For all we know, there could also be a group of friends she teams up with in the context of Tekking 101, but without more information, it's just speculation.
One idea could be a crossover with the One Piece world and the Naruto universe. Kizaru could end up in Konoha and his light - based powers would be a mystery to the ninja there. They might mistake his abilities for some new form of ninjutsu.
First, decide on the world or character you want to crossover with Kizaru. For example, if it's the Star Wars universe, think about how Kizaru's light - based attacks could be compared to lightsabers. Then, come up with a plot. Maybe Kizaru is sent to a different galaxy and has to find his way back home while getting involved in the Galactic Civil War.
There's a fanfiction called 'Kizaru and the Lost Treasure'. Here, Kizaru stumbles upon a map that leads to a long - lost treasure. Along the way, he has to face off against other pirates who also want the treasure. His speed and light abilities give him an edge in the battles that ensue.
