H-How did you do that just now!?

Erm...

Spiritual power, yes!

Ah, right! Spiritual power!

STAMINA

STAMINA

SPIRIT

When people move around, they burn stamina, right?

Spiritual Power is like... the spirit version of that... maybe?

Even if you're at your limit, when you're full of motivation a whole lot of energy comes out, right?

But, yeah, I can only use it, like, two times a day.

And Mieru's spiritual power is also strong...

You can guess the rest, can you not?

Spiritual power lets even simple people be strong, yes...

So, Spiritual power...

one could simply think of it as the power of your spirit.

Indeed,

All you gotta do is think about controlling that, and that'll do it!

So what I did before was just whacking spiritual power into my hand and doing a hand-strike.
