How a Bottom-Tier Summoner Scorned as 'Unable to Summon Even Small Fry' Using a 3cm Diameter Summoning Circle Limit Ring

Ranma dreams of becoming a summoner after a summoner girl saves him when his hometown is attacked by a Fallen Angel. He vows to do everything he can to become someone worthy of her. In a world where a summoner’s ability is judged by the size of their summoning circle, Ranma is scorned for producing one only three centimeters in diameter. He trains relentlessly, then discovers a secret method and succeeds in summoning a beast. Together, the unlikely partners display extraordinary synergy as Ranma sets his sights on becoming the strongest summoner with the smallest circle.
