Zero no Tsukaima - Volume 15 Chapter 4

Summoning ceremonies can freely call forth even “those which lurk in the depths beyond the gods”. One boy has top-level abilities even among the cutting-edge summoners who can use those ceremonies. He is Alice (with) Rabbit aka Shiroyama Kyousuke. But this strongest boy summoner has a single fatal weakness. Certain “cursed words” spoken by girls: “Help me.”

When Kyousuke hears those words from Meinokawa Higan, a girl brought to the verge of death, he throws himself into a city where three great summoner forces clash!

Roy’s life was nothing special. The only thing commendable was the last few moments when he saved a mother and her child from a drunk driver.

I swear that if I don’t exterminate your He family, I, Lin Haoxue, am even lower than a demon beast! Therefore, the most powerful He family situated in the capital of Wuhuan Empire became the first challenging target of this twelve-year-old good-for-nothing Second Young Lady from an average family of Taixing town.

Even without any profound power running in her veins, the adventure she had in Mount Bilu’s Falling Cloud Stream activated her eight elemental profound veins. Overnight she went from a having a garbage constitution to being a Middle-stage Profound Master realm cultivator, and since that fateful day, Lin Haoxue started down her journey of otherworldly domination!
