Flying Raijin itself would probably be best to avoid for a genin. However, you could probably come up with a simplified teleportation technique. Maybe limit the distance it can travel to within the user's line of sight or something similar. This ability can be through use of an item/scroll, or possibly a hiden technique unique to the clan.

Kunai manipulation sounds like it could be a metal manipulation. Though I've made a similar style of ability that is just a clan hiden technique. See this page for how I made mine (Sword Transformation). It may help you think of how to build your own.
