Ougi skill evolution?

[Akuii]

Is there a way to skill evolve ougi skills?

I currently have my Rapid Storm V, max level and the skill has a double border, yet I'm unable to evolve it.


My Momotarou is also maxed out at the moment.


Anyone have any ideas?

Rapid Storm evolves from 5 to 7 directly. There is no rank 6.

[Akuii]

So I'll need a triple border or I'll just need to wait until Momo is higher rank?

[Otonashi]

Momo just needs to be able to evolve skills to rank 7, no double border is required.

that's odd I guess some skills doesn't evolve. I heard from some people you can't evolve ougi but I got mine to evolve on this vid.
