Just as he has been told, lightning precisely. There is a stutter in his movements, the Dragon attempts to make its way to the tree tops but fails as the toxins activate. Ordinarily, servants are unaffected by natural chemicals or components such as this that invade their spirit form - however Mizuki is not inherently so human, and these toxins are not so inherently usual.

After the struggle of willpower against the feeling of lighting sporadically thrumming through the extent of his inner body. The warm boiling feeling of madness and rage that kept itself within the confinements of Adronight - the self-installed cursed armor. Seems to feel lukewarm but even with that feeling. The anger within him does not subside, but the body succumbs and he slides down through the branches of the forest, and slams with a loud shaking thud into the roots of the forest.

What ever is he feeling? What always does, why does he exist, why does he exist, why does he exist?

He will stay like that until his energy is fully depleted. Return to his normal form, a broken man, a worthless servant. Then - turns back when the forest is angry and makes him relive all that he hates and fears all over again - hopefully there Mizuki will impart on pity and paralyze him again.
