It's hard to say who would win. If Lily is very fast on her feet and has a good knowledge of the Hogwarts grounds, she could have an edge. But if one of her friends has a special magical ability like being able to fly without a broom for a short time, that friend might win. It really depends on how they use their skills and the environment around them.
Lily's friend who is really good at potions might have an advantage. They could create a potion that gives them enhanced speed or the ability to become invisible for a short period. However, Lily could also be a strong contender if she has been practicing her dueling skills and can use defensive spells to keep her friends at bay while she moves to tag them. There are so many variables that it's difficult to determine a clear winner.
They could also face some challenges during the tag game. Maybe there are magical creatures that get in the way or some enchanted objects that cause unexpected things to happen. For instance, they might accidentally trigger a spell on an old statue that then starts chasing them, adding an extra layer of danger and excitement to their tag game.
Obviously, Lily is one of the main characters. And her friends, though we don't know their names yet from just this title, are also main characters. They are likely to be students at Hogwarts with different personalities and magical abilities.
It could be about Lily and her friends exploring the magical world of Hogwarts in a game. Maybe they are on a quest to find a hidden magical artifact within the castle. They might face challenges like solving puzzles created by the Hogwarts founders.
Well, Cedric Diggory could be a friend. He is popular and kind, and would welcome them. Cho Chang might also be their acquaintance or friend as she is friendly and sociable. And then there are the Hufflepuff students in general. Since Hazel is very kind - hearted like many Hufflepuffs, she could easily make friends within that house, and through her, Percy and Piper could also have connections with the Hufflepuff students.
Sakura might become friends with Hermione. They both are intelligent and interested in learning, so they could bond over books and studying magic. Sasuke, well, he might be a bit more aloof, but he could end up having an odd friendship with Harry. They both have a sense of responsibility and a past filled with challenges, so they might understand each other on some level.
However, if it's a game that requires cunning and manipulation, like a Slytherin - style strategy game, Draco might come out on top. He's been brought up in an environment where such skills are valued and taught.
Hermione's friends would likely be very excited. They might plan some special activities for her parents. For instance, they could arrange a little tour of the Forbidden Forest (from a safe distance, of course). They would also share stories about Hermione at Hogwarts, how smart she is and all the adventures they've had together. And they would be happy to answer any questions Hermione's parents had about the wizarding world.
It could be James Potter. Since they have a relationship in the original story, it's possible that in the fanfiction, he is the father.
In my opinion, Hermione Granger would likely win. Hermione has demonstrated time and time again her ability to think on her feet and use her knowledge in creative ways. She's not just book - smart, but she can adapt magic to different situations very quickly. Lily Potter was no slouch, but we don't have as many examples of her in complex magical battles. Hermione has faced Death Eaters and all sorts of dangerous situations and come out on top, so I think she'd be the victor in a duel against Lily.
Sakura would adapt to Hogwarts quite well. Her intelligence as a ninja would translate into being a good student in Hogwarts. She'd be able to memorize spells and potion recipes easily. Sasuke would take a bit more time. He'd be cautious about the new environment, but his natural talent would eventually help him adapt. Naruto would be all over the place at first. But his positive attitude and eagerness to learn would make him fit in. His friends would be influenced by his energy and start to feel more at home in Hogwarts too.
