I'm the Owner of the Pokémon Day Care In the World of Pokémon - Chapter 104: Crucial Point

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

When it comes to chasing a male god, who does it best? Please come to City C and find Miss Morris.When Ariel Morris was young, she chased after Jimmy Season, the top male idol at Scenic Hill High School, and secured her place as the number one on the female-chasing-male leaderboard, a record yet unbroken.Time passed, and eight years later, upon meeting her male god again, Ariel Morris once more embarked on her long journey of pursuit.After marriage, there was an interview by reporters with the sweet and loving couple.“May I ask, who chased whom?”Ariel Morris laughed charmingly, “Of course… I chased him!”The crowd was shocked!Young Master Seys lightly smiled, “Sometimes, chasing someone doesn't necessarily require hands-on effort, just a little brainwork. And clearly, my wife's IQ is lacking, and her emotional intelligence is zero.”Miss Morris: “……”So, in this emotional pursuit, who really chased whom? And who first had feelings?……—Many years later, does the person you love still love you?—It turns out, what is constantly on your mind will indeed have a response!Arlo Seys & Ariel Morris: Serenity Time, Seasonal.May the wind dye white frost, and may Seasonal never fade away Ariel!

[A Naruto “OC-SI” Fan Fiction]Make the best of what you have, they said... But what I am supposed to do when the best I have are red-eyed freaks, a child who's supposed to be the jailor of the most dangerous being in the world, a snake creep with serious boundary issues, and a whole world of super soldiers with licences to murder.And you know the best part? None of them like me so much...Oh shut it, old man! Take that Will of Fire and shove it up your—Yeah, this second swing at life isn't panning out...---------------------------------------------------------------What to expect:- Gradual strength progression. Meaningful growth. The MC is a normal guy dumped into the Narutoverse, starts out weak and has to work and struggle for everything he gains.- “Slow” paced. My writing style is a zoomed-in look camera that follows the protagonist. It might seem slow, but I ensure something is always happening to progress the plot forward.- Gritty and often bloody fights and actions scenes with a focus on taijutsu—you'll see individual combat, team fights, and large-scale battle.- A different take on the Narutoverse. The world is full of superhuman mercenaries with liscenes-to-kill—that along with the protagonist's struggles paint the world in a much darker light.- Additions and expansion to the “chakra” power system. I consider myself a conservative when it comes to adapting the power system—and aim to retain the original feel while highlighting the best parts.- The Outsider's Resolve version of Narutoverse uses the [Naruto Manga] as the base—with additions from anime, books, and even Boruto (though very less likely).

The salaryman who had a dream of becoming a CEO has finally succeeded.

However…

There was no one. No one was around to celebrate his success. Then on his first day of work, news of the death of a former colleague that he had laid off came. Additionally, his family left him, who was only concerned about the company.

The life he thought was right crumbled right in front of him. Where the heck did it all go wrong? Then, another opportunity came for Han Yoo-hyun, who had plunged down into despair.

This time, for sure. He was going to live properly. He was going to change it all with his whole being. The new life that Han Yoo-hyun was creating.

That valued life that will outshine any other is unfolding now!
