MTL - Martial King’s Retired Life - ~ About the unpleasant beginning and end of September (If you are not interested in the author's Luo Liba, please don't click in * 3)

The story revolves around Charles Karino, a Levaamu Empire mercenary aerial pilot who mans the twin seater reconnaissance seaplane Santa Cruz. One day, he receives a preposterous assignment: to fly solo over 12,000 kilometers of enemy waters to protect a girl named Fana del Moral. Fana happens to be the next in line to the empire’s throne and a girl possessing beauty “equal to 5,000 beams of light.”

This is a standalone book. There’s another series under the name “To Aru Hikuushi e no Koiuta” (Love Song for a Certain Pilot) set in the same world, but in a completely different place and with different characters.

The world was once at war with 10 alternate worlds. This was known as the Concept War and our world won 60 years ago. All of this was concealed so no normal people are aware of this fact in the current time.

After the death of his grandfather, the high-school student Sayama Mikoto is suddenly summoned by the giant corporation IAI. He learns this world is headed for destruction due to the acceleration of the Minus Concepts. To prevent this, negotiations must be undertaken with the survivors of the other parallel worlds so their 10 concepts can be released.

And so Sayama is caught up in the final battle to clean up after the Concept War which left behind so much enmity.

Yu Yuehan is the usual rich, perfect, aloof president—the richest man in City H; but one day, a female toddler suddenly appears in his life as his daughter! Despite being certain that he has never touched a woman before, DNA tests certify that the toddler is his! He soon becomes a good ‘daddi’ for the little toddler, Xiao Liuliu.

Two years later, for some inexplicable reason, Xiao Liuliu becomes very fond of a trial nurse, Nian Xiaomu, hired to take care of her. Nian Xiaomu has a strong personality and refuses to let anyone bully her. Constantly wary that anyone might cause harm to his daughter, Yu Yuehan keeps a constant watch over Nian Xiaomu. However, his black-bellied daughter has plans for her father up her sleeves… Over time, Nian Xiaomu reveals her charming side bit by bit; and for the first time in his life, Yu Yuehan is drawn in by this mysterious woman…

“Daddi, you are so handsome!” Xiao Liuliu blushes.

“Daddi, I want hugs!” Xiao Liuliu coos.

“Daddi, I want a younger sister! Quick make one with Mommi.”

“Daddi…”

Yu Yuehan says in a deadpan fashion, “I have never slept with any woman! How can I have a daughter!?”

“Did Mommi sleep with you without you realizing it?”

Yu Yuehan: “…”

After the Catastrophe, every rule in the world was rewritten.
