In the end, Ritsuka gives Gudako 2 more items before letting her go to the airport, Potara Earring(Dragon Ball) and Angel Player Program Installer(Angel Beat).

Gudako sees the earring in the wonder of its mystical abilities before equipping it saying that it has a cute design. After all how often do you see an artifact that allows for two people to fuse into one?

'This will also make me never forgetting it while most people just waved it off as simple accessories' Gudako thought

As for the Angel Player Program Ritsuka only instruct her to give it to someone that she trusts in the hope she giving it to Da Vinci, because he knows that Gudako is hopeless with English…

"I am not that hopeless!" Gudako pouted

Ritsuka noted the program will be a groundbreaking discovery that will turn the magic world upside down which is one of the conditions stated by ROB for this second life while giving Gudako leverage against arrogant Magus as the sister of the Angel Player Creator, killing two birds with one stone

Ritsuka sighed, the truth is Ritsuka want to give her Time Ring(Dragon Ball) but he didn't know how will it interact with the Rayshift Coffin…and he really didn't want to tempt Murphy, for all he know when he brought that out Goetia will appear in his backyard…

Looking at his computer and checking the time for flight Ritsuka found that it took around 18 hours for a flight from Japan to Antarctica

"18 hours huh, this is assuming it was a normal flight" Ritsuka start to think "for all, I think the United Nations has a secret plane or something similar because of how high-level secret Chaldea is…so maybe it can be cut around a few hours"

"So that means I have at least until tomorrow at best and tonight at worst before the earth turned into living hell" Ritsuka sighed and look at his computer "well, time to become so OP like no one ever was"

With that Ritsuka power leveling using Record Manifestation started

"First thing first, I need to make sure even if my body explodes because of consuming wrong consumables will be still okay…"

Ban Fountain of Youth(7 Deadly Sins) consumed! Ritsuka gained Immortal Body!

"Next I need to make fate in my favor, basically my own plot armor, and considering I already given my sister Telos Karma there is only one item that I can think of…"

Mirror of Samsara(ATG) obtained! With that Ritsuka quickly dropped a single drop of his blood, making himself it's master and quickly equipping it

"After that, I need an infinite storage space that can be used to contain even some plants and cannot be stolen by anyone"

Sky Poison Pearl(ATG) obtained! With that Ritsuka quickly dropped a single drop of his blood, making himself its master and absorbing it into his soul

"Next I need a versatile power that is easy to use"

Chakra Fruit(Naruto) consumed! Ritsuka eyes awakened Rinne-Sharingan and his body develop Chakra Pathways! "No Byakugan? Well, considering that Byakugan is part of the Otsutsuki it was quite understandable. Considering that Chakra Fruit is the amalgamation of power and DNA from alternate earth isn't that mean I am Alternate Arch-Type Earth? Sadly, I am not as strong as the normal type because this Chakra Fruit is picked before drying the alternate earth dry"

Ritsuka noted that as long he let his Rinne-Sharingan active his chakra control reach master level but when he turned it off he didn't have control over it. "Well, for now, let us keep it on at all times until I can learn to learn chakra control on my own…it was a good thing Rinne-Sharingan didn't cost any energy to activate…"

"The next is I need a fit body…not that my current body is bad but it just to not build for a prolonged fight even though my stamina is quite normal for someone my age"

Super Soldier Serum(Marvel) and Vita rays machine obtained! Vita rays machine is put in the garage! "Hmm I need more than one person to operate the vita rays machine but I can't trust anyone to help me operate it…I also can drink it without the help of the vita rays but my personality will become twisted"

"That only left with…Shadow Clones Technique!" with that around 5 clones appear from a puff of smoke "you guys know what to do right?"

The clones nodded in affirmation and quickly fill their post

The machine reminded Ritsuka of Full-Dive machine that he usually see in some Sci-Story, taking a deep breath he readied himself because he know that it will be painful experience if Steve Roger screams can be used as a reference

"This month electricity bills going to be expensive" Clones#1 commented

"The world gonna turned into burning hell at any moment and you worry about electricity bill?" Clone#2 ask incredulously

"To be fair there is no salary for saving the world" Clones#3 smiles wryly

"Hey be serious" Clone#4 commanded "It's starting!"

"Original make sure to hold your screams!" Clone#5 shouted, "we didn't want Raiga underling to come here to check on us!"

"Noted" Ritsuka answered

Pain, pain, pain, painpainpainpainpainpainpainpain. That was the first thing that Ritsuka know the moment the machine started. It was a really painful experience, the various muscle in his body is convulsing, his whole body and bone is aching.

Ritsuka really wants to scream but he knows if he screams, he can't explain his current situation to Raiga. After all, Raiga really dote both of them and he really didn't want to make him worry

After around 3 minutes the process ended. Going out from the capsule pod, all the clone's breath hitched. Ritsuka is no longer skinny like the clone, his body is clearly buffed, it was showing when his previous baggy clothes are about to be ripped at any moment.

It was no bodybuilder level but Ritsuka know it was the golden ratio for his own body to attain maximum benefit

The clones quickly compare themselves in amazement before dissipating in a puff of smokes

"Now I need passive protection in case I am being caught off guard"

Fafnir Blood(Nibelungenlied) obtained! Fafnir blood is put in the bathtub! Ritsuka quickly dive into the tub making sure all his body is covered by the blood, he is also extra careful to make sure that he didn't accidentally drink it, sure the dragon bloodline is awesome but if Siegfried is any indication it is the dragon blood will slowly curse him and turning him into Fafnir which while awesome but gonna impractical…at least until he can control the transformation at will, so it best to skip it

Checking his skin with the new glowing tattoo(?) Ritsuka noted that it should be as hard as dragon scale "Hmm, the glowing tattoo is reminding me of Nasuverse Siegfried but I am clearly taking it from Nibenlungenlied, is this because in this universe it was a real tale so it brings out the original blood from the tale or it was because this universe rule? Next time when going to another universe I should check and compare the result"

"For now let us take another Fafnir blood from another universe to get the dragon bloodline"

Fafnir Blood(Shinmai Maou Testament) consumed! Ritsuka gained dragon bloodline and Banishing Shift! "A bloodline technique to banish someone into Zero Dimensional Space essentially erasing their existence! What a terrifying ability!"

"As for this phantom pulse above my heart…is this the legendary Dragon Core? What a terrifying mana generator!…for now let us turn it off, my energy control using Rinne-Sharingan is wavering due to the amount of mana it generated!"

"Anyway now that I already covered versatility(Chakra), body defense (Fafnir Armor), Stamina(Serum), Vitality(Fountain of Youth), and lethal attack power(Banishing Shift) …for now I should have the nonlethal version of attack power" Ritsuka start to search "it should be easy to use and didn't use mana or chakra in case I exhausted both of them"

Demon Extract(Akame ga Kill) consumed! Ritsuka gain immunity to cold and the ability to control Ice! Unknown to Ritsuka if he drinks Demon Extract before Super Soldier Serum his mind will be destroyed and turned insane. After all, he is no Esdeath, he is just an ordinary high-school graduate student, it was a good thing that Super Soldier Serum also strengthened mind and mental fortitude

Truly the Mirror of Samsara already showing its results even though Ritsuka is totally unaware of it

'Anyway, it was enough for now…my stomach is already full after consuming strange thing even if it was for my power growth…' Ritsuka thought holding his full belly
