The plot could develop with Harry being abandoned in a big Japanese city like Tokyo. He might end up in the muggle part of the city at first and have to use his wits to get by. Eventually, he attracts the attention of Japanese wizards who are both curious and cautious about him. They take him to their magical enclaves where he discovers that there are different types of magic in Japan. There could be political intrigue within the Japanese wizarding community regarding Harry, with some seeing him as a threat and others as an opportunity. He has to navigate through all this while also dealing with his own feelings of abandonment.
She could face a lot of challenges. For one, the language barrier would be difficult. She'd have to learn Japanese to communicate and study in the new magical environment. Also, the Japanese magical society might have different views on her status as an outsider, and she might have to prove herself worthy to be part of their community. However, she is Harry Potter after all, so she would likely adapt and grow in this new setting.
Well, her Hogwarts - centered story would completely shift. Instead of going through the trials at Hogwarts, she'd be dealing with the Japanese magical schools or training systems. Maybe she'd end up in a school like Mahoutokoro, where she'd have to learn different magical techniques and rules.
He'd probably be more reserved and polite, as those are common traits in Japanese culture. His sense of honor might be more in line with the Japanese concept of 'bushido'.
The plot could develop in a way that the trivot has some connection to Harry's past. Maybe it was something his parents left for him. As he delves deeper into understanding it, he uncovers secrets about his family and Hogwarts. He might have to face some enemies who also want the trivot, leading to intense battles and chases around the wizarding world.
In this fanfiction's plot, Harry's identity as the Boy Who Lived would be intertwined with his military upbringing. He could start a sort of 'wizarding army' within Hogwarts, recruiting students who are willing to fight against the dark forces. His training by soldiers would make him a natural leader in this regard. The story would then revolve around his efforts to build this army, face the opposition from some traditional wizards, and ultimately use this new force to defeat Voldemort in a more strategic and coordinated way.
The plot could start with Harry being born on a spaceship or a space colony. As he grows, he discovers his magical powers, which are different from those on Earth. He then gets a message or a sign that leads him to a quest. This quest might involve finding a lost magical object that has the power to save the space - wizarding community from a dark force. Along the way, he meets other magical beings from different parts of space and they form a team to complete the mission.
Well, the magic system might be integrated with Japanese folklore. For example, instead of wands, they might use something like Japanese talismans. And Hogwarts could be a Japanese - style castle or temple - like structure, with different houses representing different Japanese clans perhaps.
She would likely be more influenced by Japanese values such as respect for elders and harmony. So, instead of being as headstrong as the original Harry at times, she might be more diplomatic in her approach to problems. For instance, when facing a bully in the Japanese wizarding school, she might first try to resolve the issue through peaceful means rather than immediately retaliating.
The plot could involve Harry using his magic in a more open way around the Dursleys. They might help him hide it from the wizarding world until he's old enough to go to Hogwarts. Then, at Hogwarts, he could be more focused on learning for the joy of it rather than as an escape from his horrible home life.
The plot could develop with the female characters uniting to search for a solution. They might start by looking into ancient magic that was perhaps created or known only to female witches. Maybe they'd discover that a powerful female dark wizard from the past cast a spell that backfired and made all males disappear. And they'd have to go on a journey to reverse it.
