One idea could be exploring the backstory of an exorcist character in more depth. Maybe they have a hidden past related to the devils in High School DxD that no one else knows about.
First, you should familiarize yourself with the High School DxD universe. Know the rules, the different species like devils, exorcists, and angels, and how they interact. Then, think about your main character. If it's an exorcist, decide on their personality, their motives, and their backstory.
Big Al Macs could be an individual with a unique identity. Maybe he's someone who has done something extraordinary in his field, whether it's in art, sports, or business. Without more context, it's hard to say exactly who he is, but he's clearly the central figure in this 'big story'.
A scary El Salvador story is that of the Xtabay. It's said to be a female spirit that lives in the jungle. She sings a beautiful but hypnotic song that draws men to her. Once they are close, she either kills them or drives them insane. This story was often told to keep people, especially men, from wandering too far into the dangerous and uncharted parts of the jungle, as the unknown held such terrifying entities.
Well, it's hard to say for sure. You'd have to look into the background and the creator's statements to determine if it's based on actual events. Sometimes what seems like a true story could have a lot of creative liberties taken.
El Deafo is indeed a true story. The author drew inspiration from her own childhood and experiences with hearing loss to create the narrative. It offers an authentic and heartfelt account.
Not necessarily. 'El cantante' could draw inspiration from real-life, but it's probably embellished or fictionalized to make for a more engaging story. There might be some truth at its core, but it's not a straightforward account of actual events.
