Well, I think Ugo is an interesting character. He is Aladdin's djinn and has a very powerful presence. He provides both protection and guidance to Aladdin. Also, the character of Kougyoku is worth mentioning. She is a princess of the Kou Empire and her position in the imperial family brings a lot of political intrigue and personal growth as she has to navigate between her loyalty to her family and her own feelings. And then there's Sahsa, who may seem like a minor character at first but her relationship with Alibaba and her own little story arc make her an interesting part of the novel.
Aladdin is really interesting. He's a magi, so he has these amazing powers. He's also very kind - hearted and curious, always eager to learn about the world around him. Another interesting character is Alibaba. He has big dreams of changing his life and the world, and he's constantly facing his inner demons and growing throughout the story. Morgiana is also fascinating. She was a slave but she has this inner strength and loyalty that make her a great character.
For me, Sinbad is one of the most captivating characters. He's a very powerful and influential figure in the world of the novel. He has built his own empire and has his own plans and ambitions that often intersect with the main characters' paths. Judar is also quite interesting. He's a magi like Aladdin but has a very different personality. He's more on the wild and unpredictable side, which makes his actions and decisions always full of surprises. And of course, we can't forget Hakuryuu. His complex backstory and his thirst for revenge add a lot of depth to his character.
