From what I gathered about the power in this chapter, so three years ago, with how Kogarashi beat Garandou that was supposed to be 100m, then he was 100m+ power? And with Ouga is currently 120m, she managed to 1-shot a 100m+ Kogarashi. But then again, Kogarashi didn't block or prepare to block or anything, so his power is still unknown for now.
And the developing of this chapter, then we will probably get a Fully Prepare Kogarashi vs this Garandou then. And I'm still thinking about my theory that Kogarashi's power already surpassed Power-up Ouga but he was just beaten just because he was un-prepared. Now waiting for the battle between True Garandou vs Kogarashi.
And the mystery about the Living Yuuna-san seem like will still be sometime till we get a reveal.
