第 10 集: 真奈美解除刺客武裝並歡迎新公會成員
Masato rushes back to the guild only to find Mamako about to hand over all their money to a disguised assassin. The assassin flees, leaving a bomb, but Mamako disarms the bomb with the skill Mother's Headpat. Amante appears demanding to know why her bomb did not explode, but flees after seeing Mamako. The assassin and his team reveal they planted bombs around the city and will set them off unless the girls serve them as maids. However, their interaction with Mamako reminds them of their mothers. In the end, they agree to remove the bombs and apologize to their mothers. Mamako insists everyone share a hot spring to decide their next move, but Amante burst in, furious at losing her assassins. However, she becomes embarrassed at the girls bathing naked with Masato. Shirase arrives at the guild with all the mothers who volunteered to join their guild and clear the tower, as thanks for returning three of their sons. Amante plants bombs in the tower to kill them all, but grows frustrated when the mothers are late, and accidentally blows herself up by falling down the stairs. (Source: Wikipedia)
