Obviously, Harry is one of the main characters since he owns the cafe. There might also be his employees, like a barista who is really good at making coffee and has a great personality.
There could also be a character who is Harry's friend or family member. This person might give Harry advice on how to run the cafe better, or they might help out during busy times. For example, his sister could come in to do some baking for the cafe on weekends.
Well, it could be about Harry's daily experiences in running the cafe. Maybe it includes how he manages the staff, deals with different customers, and creates a unique atmosphere in the cafe.
Hermione would probably be a regular. She'd come to the cafe to study while enjoying a warm cup of Butterbeer latte. She might even bring some books from the Hogwarts library to read there.
The cafe might have jutsu - powered appliances. For example, a stove that heats up super fast using fire - based jutsu elements.
His friends might be in it too. They could be the ones who join Harry on his yacht trips, having fun together. Maybe there's a character who is a bit of a troublemaker among his friends, always getting into funny situations on the yacht.
It could be that they use magic to keep the pastries fresh all day. There might be a charm placed on the display case that constantly renews the freshness of the cakes and muffins. Something like 'Freshio' charm which ensures that every bite tastes as if it was just baked.
The main characters are Naruto, Kurenai, and Anko. Naruto, the hero of the Naruto series, is the one who is in a position to 'own' the other two. Kurenai, a jonin level ninja known for her skills in genjutsu, and Anko, a strong - willed kunoichi with a troubled past, are the ones who are related to Naruto in this fan - made story. Their interactions, be it in battles, training sessions, or just day - to - day ninja life, will be the focus of the fanfic.
Well, in this fanfic, Naruto might serve ramen in his cafe. He could decorate it with symbols from his ninja world, like the Hidden Leaf Village emblem. And his friends would surely be regular customers, sharing their latest adventures while having a meal.
Hermione could be a major character. She would be really helpful with all her knowledge, maybe helping Harry with the care of the magical creatures and coming up with ways to educate the visitors. Ron might also be there, perhaps handling the more physical tasks around the zoo like building enclosures for the larger creatures.
I don't know who the author of that fanfic is. There are so many fanfic writers out there and without more information it's hard to tell.
There could be students from a nearby school or college. They might come in for a quick snack or to study while having a coffee.
