The story follows Souha Sugiyado, a 17-year old ninja instructor and former ninja prodigy who was forced to retire from active duty by the wounds he suffered in his last mission. Souha's four students are all kunoichi who have all gained the rank of Elite Ninja, the highest official rank available to ninja. However, one day two Shogunate ninja approach him with the news that his four students have gone rogue and have stolen a portable modular nuclear reactor, and thus they ask for his help in bringing his students to justice.

He is a legendary business powerhouse, a King with a business empire. She is just an ordinary female student. A deal, – a paper marriage, a marriage for four years. Four years later, she turned away fearlessly. She thought that their path would never cross again, but he took her in his stride and refused to let go of everything about her, even interfering with her getting close to other men!

Because the thing living inside him 'The Echo' never sleeps.
