Peace
Aina pouted and laid back down on Leonel's chest. She was clearly very unhappy. If she had known this would happen, she would have gone too. Although she could only use Soul Force, surely Dream Force wasn't that hard to learn, right?
Honestly for Aina, she rarely used Forces other than various Weapon Force and Blood Force not because she couldn't, but because she didn't like putting her eggs in too many baskets. Spreading the wealth was good practice in most cases, but not when your task was becoming as strong as humanly possible. In fact, even her Weapon Forces were purely used in accessory to her Ax Force. So really, she only used two Forces mainly.
However, with her Clairvoyance, learning other Forces was not very difficult at all.
For example, the lightning Force she gained access to in her demon form, it progressed along easily even though she rarely practiced it much.
