The Hero King, Reincarnate to Master the Art of War ~And Thus, I Became The Strongest Knight Disciple (♀) in The World~

already resummoned the lightning beasts and they were standing all around him.
What a cunning man.

「Prism Powder, a secret drug that’s basically an extremely concentrated composition of Prism Flow.
The Ironblood Chain Brigade has ‘em, y’see, they give me some to coax me into joining them.
Even so, its effect was too weak when used on Humans but if Highlanders used ‘em, this happens.
I mean, we’re used to the Prism Flow down here, after all.
What I’m saying is that they’re taking it too lightly is all.
It’s a pity that things turn out like this.
Now he’s just a mindless beast.」

Leon then shrugged at Rahal who was now a magic stone beast.
There was a heartfelt contempt towards the drug within his gesture.

「…Any way to revert it!? Can’t he change back!?」 「Hold it right there, Eris, you want to save that stuck up brat? Death is his only salvation, just so you know.」 「Even so, we can’t have a Highlander die in this place!」 「Wow, you sure hold onto that status quo.
I mean, like, you’re asking me if there’s any method to revert him? If there was, we can just use it on every magic stone beast and voila, world peace!」 「Uu…」 「Well, you can just push all the blame onto me.
Tell them that Leon had defected to the Ironblood Chain Brigade and did all this! Anyways, I’ll make my getaway for now.
It would be embarrassing if I get caught as soon as I decide to leave the Holy Knight! Well, laters!」 「Ah! Wait, you!」 「Explode!」

All the lightning beasts exploded at the same time with such a bright flash that everyone within the vicinity was blinded for a moment.

「Kuh!」 「Crap, he ditched us!」

By the time Inglis and Eris regained their sight, Leon had already made his escape.
Capturing Leon and making him confess everything at the Royal Capital would be the best outcome but… it was simply impossible to leave this beast-Rahal to its own devices.

Inglis had to put aside chasing after Leon.
If she couldn’t find him, she’d have to ask Eris to speak for Ymir and explain everything.
It might not be as effective as having Leon, the perpetrator himself but if it was spoken by a Hyrule Menace, legitimacy to some degree could be expected.

「INGRIIIISSSSS!!」

That shriek didn’t sound like it was seeking for salvation at all.
Although it was hard to deny that this was a just punishment for Rahal, who had grown into a detestable adult, all Inglis could feel towards him right now was… pity.

「…Due to my past relationship with him, let me be the one to put him to sleep.」

Inglis said regrettably as she stepped towards the thing that was once Rahal.

Al- hahahah! I knew it! The Highlanders are the ones who actually made the magic stone beasts!Mab- Let me get it straight.
So, Leon came to Ymir while bringing a suspicious white powder with him from the capital.
On the way, Rahal found that suspicious white powder, thinking that it’s some good stuff, and stole it.
Later this night, since he’s gonna have some fun time with Inglis, he’s thinking that might as well do it while he’s high.
So, he snorts that good stuff.

Is that how it went? Wow, author, for making Rahal a junkie on top of all the bad qualities he already has.
