Humans who is on top of the food chain suddenly struggles to survive in this new world. However, due to their overwhelming resillience and great reproductivity, the humans came to have a solid foothold in this new era.
...
In a remote island of Japan, a small wooden boat floated for God knows how long... under the extreme heat of the sun and the trecherous waters of the ocean, the boat floated and dance through the waves.
...
"yo old man!"
"how's your back?"
"thank you for your concern lad, but I aint croaking just yet, hahahaha..."
Ryoma Tatsuki also known as Old Man, he prefers being called that, he is currently walking by the shores as his daily afternoon routine. Though called an old man since he is currently 500 years old, Ryoma is still on the prime of his life. He is handsome with tall nose, fine sculpted jawline, black shiny hair and fit body, standing at six foot tall. Nobody knows his origins, he arrived just a few months on these island and is working as a shipwright.
"ah, fresh air..."
"there is no better way to freshen up a tired mind than walking by the shores, listening to the waves and..."
"huh... a boat?"
as he looked to the horizon, he noticed a boat... without delay he disappeared from his spot and teleported to the boat.
Creak... the sound of the wood, as he appeared at its deck...
" these boat is well made..."
As he walked through the boat, he saw an emblem that resembles a red crysanthemum...
"how is a royal ship became this battered?"
Ryoma became tense, took his phone and checked...
" seems like is the missing ship of the princess...
then he moved faster as he scanned the whole boat
huh..."
As he looked around, he found magic bullet holes on the deck... he became more tensed and nervous
"bodies? assasins..."
he came closer to the bodies...
whooosh...
a kunai flew and Ryoma easily dodged...
Ryoma identified the attacker, "prin...cess!"
He immediately rush to her side, and scanned her
"who... are... you...? d...d...did... you... come... to... kill... my... son...?"
her eyes are blurry, gasping for her breath, she said trembling.
Ryoma trembled in rage, he clenched his fist tightly as blood flowed on his palms, as he looked at her condition. He gasp for air and looked at the princess, she is only alive due to pure willpower... his rage builds up in his chest but he didnt show it
"Hiyori its godfather..."
tears fell from his eyes as he looked tenderly at the dying princess
"i..i... dont have much... time... to...to... live... please... godfather... save my... ryo"
The princess looked lovingly at her child and made her last breath...
"its a miracle, that you survived this long, your highness... Hi..Hi...yori" he made a deep bow as he cried silently and closed her eyes, taking the baby gently into his arms...
the baby did not cry, nor did it move, its as if he is observing and studying Ryoma... he moved his hands overthe princess body and it vanished from its place...
he flicked his fingers and all the clothes of the assasins disappeared as a black flame swallowed them. The bodies have no marks and most of them have their tongues cut prior...
"this is well planned assasination..."
Ryoma found a letter, he opened it... dried blood on the paper is visible but the written words are elegant and clean...
"i guess this is her highness letter to the boy..." then he read through it
as he run through the letter more grievance filled his chest, then he looked at the boy, and it also looked at him with his deep black eyes.
He smiled, wiping his tears and laughed, "hahahaha... I Ryoma Tatsuki shall become your guardian, good eyes... like my mother and sworn brother you inherited the true blood of a Minamoto..."
after making a slient prayer, he flicked his fingers and the boat burst into flames, leaving nothing but dust and blended into the ocean waters.
he flew above the island holding the child in his arms...
"i guess living here is not possible anymore..."
then he vanished in to thin air, leaving no traces behind...
....
at the shores of the island a red painted warship docked...
" reporting general!"
a soldier saluted to a tall burly man
" any news of the missing royal ship?"
"general, by our gps, the ship should have floated to this seas, however after scouring the whole thirty mile radius and diving to the sea, no traces have been found"
then the general looked up to the skies and tears fell to his eyes.
"it seems the gods wanted our empire to perish, by killing the last heirs to his majesties throne."
...
at the royal capital...
"your highness, the ship where the princess was last noted, have vanished... the navy scoured the thirthy mile radius from where the signal was last noted. However no traces have been found."
the emperor, didnt move. He looked deep into the horizon.
"Hmnn..."
"youngest brother, dont worry... your grandson is safe with me. however i am not able to save your daughter... Hiyori... The ship was ambushed by assasins and the princess stayed alive for ten days nursing her child.
when i saw the ship, there are bodies of assasins on it, the princess cling to her life, but her wounds are horrendous and i cant do anything about it. Be careful around the palace, something dark and evil lurks that wants us to fall."
then the transmission ended...
"your majesty?"
the guard asked
"you may take your leave..."
He took a deep breath and tears dropped slowly on his cheeks, "my daughter, rest in peace, your son is in good hands..."
then he sat on his chair of his study "eldest brother..."
"yo brother"
the emperor sighed, his eldest brother never changed...
"please raise my grandson, i will settle everything here before i retire my position and pass it on to him..."
"just do pay Ryo a regular visit, i dont want him to not know his biological grandfather..."
"yes, i will always do..."
"you better old friend or i will drag you here at my place..." then Ryoma blocked his transmission
"thank you old friend" he knew Ryoma too well, he lived and trained under him during his younger years and learned all his crafts from the man... He, Ryoma and his second sister, adventured and fought together until he claimed his rightful throne.
"now that Ryo is in the safest place in all Japan, with two demigod protectors by his side, i can now start cleansing the empire..." then a sharp glint appeared on his eyes, burning with great pain from the loss of his only child, Hiyori.
...
Ryoma appeared in a forest at the foot of mount fuji, he slowly walked to its depths. A huge red shrine gate came into view at the middle of the forest and two men sat meditating on each column, as they felt Ryoma nearing they held onto their katana, ready to slash, but as they were to draw their blades.
"looks like your edges have dulled boys...
it took you five hundred meters before you are able to feel my presence..."
The men opened their eyes and saw the handsome man carrying a child and opened their eyes wide...
Ryoma appeared behind their backs and hit the back of their heads with a slap, and they both stumbled on their knees.
"we are sorry my lord, after one hundred years your spirit and strength never fades..."
"yeah yeah, stop it with those boot licking, you are being bad examples for my grandson."
Then he looked at Ryo chuckling...
"don't be like these two Ryo... such a shame for warriors"
but deep inside he felt happy, since the two were able to improve their senses, other warriors would never be able to detect his presence. Thus being able to detect his presence when he is five hundred meters away from them is a great feat already.
The guards looked at each other and scratched the back of their heads.
After the world changed, there are twenty known demigod level masters around the new world, ten came from humans and ten from other races.
The Japanese Empire have one known demigod, the emperor Kisame Minamoto. However like any other empires, Japan have its own hidden demigods, and Ryoma is one of its hidden demigods.
"meditate and train harder, i dont want pests entering our lands because of incompetent guards, hahahaha..."
"yes my lord" the two kneeled on one knee as Ryoma carrying Ryo walked towards the Shrine gate.
...
After a while he appeared on the sky above a city, surrounded by hundred meter tall walls with four thousand meter tall pagodas on the four corners of the walls and a huge shinden- zukuri mansion at the very center of the city with six cornered ten meter walls, and each corners with twenty neter tall pagodas. The whole place is around a one hundred thousand square kilometers, there are four cities on each corners with mountains, rivers and lakes within the confines of the walls.
