In this fanfiction, it might be that the wizarding world is in a state of chaos due to some ancient dark magic being unleashed. Harry, feeling the weight of the situation, starts singing 'This is War' as a declaration of his determination to stop it. His singing could have magical effects, like inspiring the portraits in Hogwarts to come to life and fight alongside him.
One possibility is that Harry, feeling out of place in the wizarding world, uses the song 'This is Me' as a form of self - expression. Maybe he's at Hogwarts during a time when he's being ostracized by some students or the media because of his connection to Voldemort. Singing the song could be his way of showing that he won't be silenced and he will be true to himself, despite all the challenges.
One possibility could be that Harry discovers his love for rock music during his time at Hogwarts. Maybe he forms a secret rock band with his friends like Ron and Hermione. They could perform at the Hogwarts parties or in the Forbidden Forest when no one is around. The lyrics of their songs might be about their adventures, fighting Voldemort, or just about the magical world in general.
Well, it could be a really wild plot. Maybe Harry discovers he has the ability to use his magic to make demons sing, and he uses this as a way to defeat Voldemort. For example, the demons' singing could have some kind of magical effect that paralyzes the dark forces.
The antagonists could be a group of corrupted Ministry of Magic officials. They have turned to the dark side for power and are trying to rewrite the laws to suit their evil plans. Harry, being the hero, sings 'This is War' to expose their wrongdoings and fight against their tyranny.
Maybe Harry discovers a magical opera house in the wizarding world and is drawn to sing like the Phantom. He could use his magic to enhance his singing and create a whole new experience for the wizarding audience.
Well, it might be a really wacky plot. Maybe Harry Potter is in a magical classroom where he has to use his singing skills to remember the periodic table. He could be competing with other Hogwarts students in a sort of magical science fair where the best singer of the periodic table elements wins a special potion or a magical item.
Well, it could be about Harry Potter secretly loving muggle music and one day he just starts singing it in the Gryffindor common room, much to the shock and amusement of his friends.
One possible plot could be that Naruto is in a situation where his village is on the brink of a major conflict. As he sings 'This is War', his voice somehow empowers the villagers, giving them the courage to face the approaching enemy. The lyrics of the song might inspire them to fight for their freedom and way of life.
One possible plot is that a new character, perhaps a transfer student from a far - off magical school, brings with them the knowledge of the song 'Unravel'. This character has a special connection to the song and believes that Harry Potter is the only one who can truly sing it in a way that will unlock a great magic. Harry is initially hesitant but eventually gives in. As he sings, it awakens an ancient magic within Hogwarts that has been dormant for centuries, and they all have to deal with the consequences, both good and bad.
It could be about Harry using Queen's music as a form of magic. Maybe he discovers that singing Queen songs can cast unique spells or defeat dark forces in a different way.
