The unexplored summon://blood-sign

Through the use of advanced summoning ceremonies, practitioners possess the power to freely call forth entities that lurk in the unfathomable depths far beyond the gods themselves. Among the cutting-edge summoners who wield these rituals, one boy stands at the absolute pinnacle. Known as Shiroyama Kyousuke, or by his alias "Alice (with) Rabbit," he is recognized as the strongest summoner of his generation, possessing abilities that far surpass his peers. Yet, despite his overwhelming power, this prodigious boy harbors a single, fatal weakness: an uncontrollable compulsion triggered by a specific phrase. Whenever a girl utters the cursed words "Help me," he is stripped of his detachment and forced into action. This vulnerability becomes his undoing when he hears that desperate plea from Meinokawa Higan, a young woman pushed to the very brink of death. Unable to ignore her cry for salvation, Kyousuke throws himself headlong into a violent conflict, plunging into a city where three great summoner factions are locked in a devastating war.
