That Time I got Reincarnated As A Dragonoid Slime In Tensura as Rimuru

Diablo's Little Adventure

Diablo Pov:

I Am Diablo, Named By My God And Master Rimuru Sama.... My Faithful Encounter With Him Was Truly Blessed....

About 70 Years Ago I Fought A Human Now Known As Shizue Sama, Rimuru Sama's Wife.... At First I Was Just Doing The Contact Of The Human Who Summoned Me To Find Something Exciting.... Then I Found Out That The Mask Shizue Sama Was Wearing Was Something Beyond Time.... It Was Far Older Then Me.... A Being Who Has Lived From The Start Of Time.... And Finally I Had Found A Meaning Of My Life... To Find The Source Of The Mask And Follow That Person.... Hopefully So I Can Find The Truth About The World.....

After My Contract Ended I Spent About 68 Years Following Shizue Sama.... Then I Found Him.... Rimuru Sama.... Ahhh Such A Beautiful Name.... Blessed By The Gods.... He Is Handsome,Beautiful,Hot,Sexy, and Blah Blah Blah....

(After 3 Hours Of Complimenting)

After Shizue Sama Met Him The Mask Started To Respond To Him.... And After He Touched The Mask It Had Broken From The Time Stop State.... The Mask Had Started To Catch Up To Our Time.... And I Finally Found Him.... The One Who Made This mask.... My New Master....

At First I Was Watching Him But When I Started To Follow Him, He Sometimes Looked At My Direction As If He Knew I Was Watching.... And After The Long Awaited Moment I Answered His Call...

As Expected He Knew Who I Was and I Was The One Watching Him....Then Even Though He Had Not Only Defeated The Orc Disaster By Himself Which Caused Him To Lose Most Of His Magicule But Even After That He Gave Me My New Name.... Diablo...

Ahh.... Such A Bliss I Had Found The Moment....

Then After Serving Him For 1 Year He Had Faced A Gruesome Reality.... But Then He Didn't Hesitate To Do The Killing Of 200 Thousand Soldiers To Evolve Into A Demon Lord.... But Unexpectedly He Broke The Rule Of The World And Ascended As The 5th True Dragon Of Existence.... It Made Me Realise Again That Choosing Him As My Master Was The Right Decision...

And After That I Met Her... Ciel Sama.... The Manas Of Rimuru Sama And Also One Of His Wife.... Rimuru Sama Later Explained Her Existence That Even Veldora Sama Didn't Knew...... A Very Rare Spiritual Lifefrom Born From My Master's Skill....

And That Now Brings Me Here, Ciel Sama Ordered Me To Make A Demon Army To Serve Rimuru Sama, So I Am Now Recruiting Greater Demon And Arch Demon From My And Blanc's Linage Which She Already Made.... Now I Have To Go Get Those 2 Remaining Primordial.... Or Should I Say Problem Child's.... Jaune And Violet Are Agian Fighting..... These Troublesome Children.....

3rd Person pov:

In The World Known As Hell Or Underworld.... There Resides Demon....
There are Many Demon Such as Lesser Demon, Greater Demon and Arch Demons....

Among The Arch Demon There Are 7 Demon Known As Primordial Demon Who Have Lived From The Beginning Of The Creation Of The World....

Among The 7 The Red And Black Primordial Were The Strongest And Both Were Fighting For Years To Decide Who Will Be The King Of The Underworld.... But Soon One Day The Red Primordial Was Summoned on The Cardinal World Where He Destroyed Two Big Super Civilisations And Named Himself Guy And Evolved Into the 1st Demon Lord To Ever Exist....

Meanwhile The Black Primordial Was Bored So, Instead Of Becoming The King Of Underworld He Began Searching For The Truth Of Existence.... And One Day He Found Him And Now Is Named Diablo, Formally Known As Black King Noir, Or Primordial Black....

That Aside Among The 5 Primordial The Blue And Green Primordial Became Guy's  Subordinate After They Lost To Him... Meanwhile The White Primordial Began Her Game In The Eastern Empire.... While The 2 Troublesome Kids The Yellow And Purple Primordial Were Constantly Fighting Each Other....
