You need to have a basic understanding of Alight Motion's tools and functions. Start by importing the manga images and then use the animation features to bring them to life.
Once upon a time in a big city, as the sun was setting, a young girl alighted from the bus. She was new to the city and was in awe of all the tall buildings. She walked along the busy streets, her eyes wide with wonder, and that was the start of her great adventure in the city.
A good 'city alight story' could be about a tourist who alights from a plane and is immediately greeted by the hustle and bustle of the city. They see the city's unique architecture and start exploring. For example, they might find a hidden alley with amazing street art and local cafes.
Toge Inumaki is important too. His special cursed speech ability makes him stand out. Also, the principal of the school, Masamichi Yaga, is likely to be important as he is in a position of authority and has an influence on Gojo and the other students. There could be other characters like the members of different clans that also play roles in the complex web of the story.
