Reincarnated as the fourth son of a noble and tamed an SS-rank dragon - Chapter 10: Demon Lord

Based on the popular Vocaloid series, by HoneyWorks, called “Kokuhoku Yokou Renshuu (Confession Rehearsal)“:

Natsuki, a third-year at Sakuragaoka High School, who holds unrequited feelings for her childhood friend, Yuu, who’s in the Film Club. However, instead of being honest about her feelings, she makes him be her confession “rehearsal” partner. Unable to say her true feelings, things start to get complicated when Miou and Akari, who are also in the Art Club, get involved! Will she ever be able to confess for real!?

A long time ago, the decayed main god space collapsed and disintegrated, and the wreckage was scattered in parallel universes, giving birth to a new space…

Countless ‘story worlds’ under control have also fallen into the void, regained freedom, runaway out of control, elevated to reality, and turned into reality.

At the same time, these “worlds” are polluted and corroded by the void, giving birth to greater fear and filth…

…

The space of birth feeds on the world.

They compete with each other, their tentacles penetrate through dimensions, invade different time and space, search for the legacy of the main god, drive the apostles to be minions, greedily tearing, seizing, devouring, and reclaiming one world after another, so that they can return to greatness.

…

The innocent eating melon and white waves with the legacy of the Lord God accidentally got involved in the parallel universe “Paradise of Fire” during a cross-border call.

After forcibly binding the demi-human blood, he became an excellent tool man who can repeatedly die, starting the legendary ‘dimension invasion career’.

Nora is shattered a month before her wedding when she uncovers her fiancé's deceitful affair. As she manages this betrayal, she discovers a deep ploy to hinder her from claiming her rightful inheritance. Devastated but determined, Nora takes a daring step to regain control of her life. Enter Demetri 'The Demon' to those who know him, a formidable man barely known to her, who offers her protection and support in return for a contract marriage to satisfy him. In a twist of fate, Nora marries Demetri to claim her inheritance and fight those who plotted against her. But as she battles her own family and Demetri's many rivals, will she be able to keep from falling for the man known to crush people beneath his booted heel.Excerpt:She had forgotten that the man was intimidating and directly challenged him.Rather than speaking, Demetri rose from his seat and approached her deliberately. Although it was a mere few steps, time seemed to stretch for Nora. When he was almost within touching distance, his hand gently landed on her knee, moving it sideways. His touch moved with a hint of a caress, and he stepped between her open legs. Nora sat there in frozen silence, her eyes wide like a deer caught in headlights.Catching her chin between his fingers, he tilted her face upwards and spoke unhurriedly,“ You are my wife.”She nodded her head slowly in affirmation while his thumb slowly traced her lip. “I have given you time to gather your emotions.”Another nod. Nora's nervousness made her lick her lips, acutely aware of his intense gaze fixed upon them.“Your reason for the marriage was to secure your inheritance and get away from under your mother's thumb.”“Yes...” Nora whispered in confusion. Her confusion was not about his statement but about the bewildering sensations coursing through her. What was happening with her?”It's time for you to fulfil your end of the contract, yes?“ He continued.”Yes,“ Nora whispered breathlessly. Why was she breathless? Had the oxygen level in the house dropped? Was the air suddenly thinning?Abruptly, his hand left her face, and she watched as he drew closer. It was then that Nora comprehended what was unfolding. All those tantalizing, heart-pounding kisses she had read about in novels were about to possibly become her reality.But the anticipated kiss didn't happen. Instead, he paused near her and commanded, ”Kiss me.“
