So yeah Rin is only 10 years old, even though she's ten she still packs a little of a punch, but what happens when she needs to do hand to hand combat with someone bigger than her? You see the problem right? So Koudo and Luki developed the Time Bazooka for her, it's big enough for her to fit inside and all she has to do is think about what age she wants to be and it makes it happen. It can only go in intervals of five however and oldest she can get is 25.

The sword of Imagination, a sword that was also created by Koudo and Luki to help Rin channel her "unique" abilities. She doesn't need it much now, but when she focuses with it correctly, it transforms into separate forms. They won't be explained until the sword transforms in them for the first time.
