Otherworldly Swordmaster

A normal high school boy saved his friend from a traffic accident and died! And for some reason, he was reincarnated!? "Waaaaah, owwwwwah" Wait, what's going on here? Reincarnated as a baby? Became a prince of the royal family in a kingdom? Could use magic before, but can't anymore? The Demon King and others are attacking together, so a hero summoning? (This is planned) "This kind of world... this is awesome!!" This is the story of a man who was reincarnated into a fantasy world with swords and magic, retaining his memories for reasons he doesn't understand! ◇◇◇◇ I'm a complete beginner at writing novels and thinking things through, but thank you for your support! The title is《Tentative》. Subject to change. Updates are irregular.
