Gaiden

Okay, so imagine you're playing a video game and you're going on a big adventure with a cool ninja guy. The main game is really fun, but sometimes you want even more cool ninja action, right? That's where gaiden comes in!

Gaiden is like an extra little adventure that takes place alongside the main game. It might have different storylines or characters, or be set in different locations. Think of it like a bonus level or mini-game that you can play to get even more fun out of your game.

Sometimes gaiden adventures are released as separate games, and sometimes they're included as part of the main game. But either way, they're a great way to keep having fun and exploring the world of your favorite video game. So next time you're playing a game, keep an eye out for gaiden adventures and see what extra cool stuff you can discover!
