(3rd POV)

Soren just finished another intense fight against none other than Artoria Pendragon, The Saber Class Servant aka the King of Knights. The Saber we all know and love and whose a total glutton when it comes to food. Soren decided to take a small break while he uses recovery items restoring his HP and MP. Walks over towards the Einzbern Mansion once again.

Soren lvl.119: 'I wonder what Kiana and Sirin are doing'?

At one of the Instance Dungeons is Kiana and Sirin are at Demon Dungeon within the forest area at night time while grinding to level up to become even stronger as Kiana and Sirin unleash their skill for a final blow.

Kiana: Let's go, Sirin!

Sirin: Hah!

Kiana: Tyaah!

*Boom sfx*

Level Up!

Kiana Kaslana lvl.78

Sirin lvl.78

The two panted.

Kiana: I am so tired.

Sirin: I envy of darling Gamer Body and Mind.

Kiana: We're not even close to his literal level.

Sirin giggle.

Kiana: What's so funny?

Sirin: The thought of us working together despite we live in two separate worlds where I have complete control of your body or at least this variant of Kiana Kaslana when she l letting me to take full control after being near to much Honkai Energy as her beloved teacher sacrifice was in vain.

Flashback Image End

Kiana grips her sword tightly. The day she met Soren It was that day Soren defeated her as Sirin; not only he saved Kiana, also Himeko who fought her in order to bring back Kiana by injection of some type of liquid that'll suppress the Herrscher of Void. Eventually defeated Otto early before shit hits the fan even more. Later is headed to another where Sirin was wreaking havoc at the city where she's been hiding at. Thankfully they were able to subdued, Soren remembers Sirin sad backstory from what Otto did to her. Soren help getting her revenge, but tries to help Sirin turning into a new leaf after he made some convincing arguments. So far everything has been going very well, Sirin started reflecting her actions and wishes she would've done better. Now travels other worlds with Soren in order to atone her sins by saving people from evil. Willingly do anything for him.

Kiana: The irony hasn't lost with me. But..... doesn't mean I fully forgive what you did or at least not yet. Then again if it was me probably end up just like in your world.

Sirin: Shall we keep going for a bit longer?

Kiana: Yeah. How about we make a contest?

Sirin: Oooh? What would be the reward?

Kiana (smirk): Winner gets to sleep in Soren's room tonight?

Sirin (smirk): Very well.

Demons started to respawn as both Valkyries got in fighting.

K, S: Hrragh!

Back with Soren who is about to face Berserker outside of the Einzbern Mansion.

Hercules lvl.121

Servant Class: Berserker

Heracles: Rraagh!

Soren: 'Shit. This is gonna be absolute hell. That Motherfucker has a God Hand: Twelve Labor. I have to kill him as many times as I can'. I'll have to go all out against this dude. Uh!

Soren quickly leap away dodging Heracles Axe-Sword. Next he brought out his Ziku Driver attached onto his waist and takes out his Ohma Zi-O and Grand Zi-O Ride Watch.

Ziku Driver!

He uses Ohma Zi-O power within the Ride Watch to Time Freeze Berserker so he will Henshin without any interruptions.

Soren: Time to try something new.

Ohma Zi-O! Grand Zi-O!

Slides into Ziku Driver empty slots then presses the button on his driver.

(Soren POV)

I look at myself with a brand new transformation never seen before. My thoughts were if only I'd have this power from my old world then everything would have been prevented. Can't change the past. I'll have to keep moving forward to save as many worlds as possible so they wouldn't go through like I did. I release Berserker from my time freeze as our battle recommence.

Zi-O: Bring it on, Incredible Hulk wannabe!

Hulk-I mean Heracles is jumping up in the air coming down with his Axe-Sword to land a hit.

Simply raised my right hand with my powers activated knocking Heracles across the forest without breaking a sweat. Couldn't help but feel impressed by my own powers to smack the mighty Heracles from Greek Mythology so easily. I chuckle a bit.

Zi-O (smirk): I am liking it. Grand Zi-O Ohma increases my stats dramatically that surpasses Berserker and the past six servants I've fought.

My precognition kick in seeing in the future to predict the Berserker attacks. Summon Zi-O swords as I combined then unleash my finisher. Golden energy blade form with kanji attach, ready myself as Berserker moves extreme speeds after he launches himself.

Finish Time!

Zi-O: 'I can see your every move'!

King-Giri Giri Slash!

*Slash sfx*

Slice Berserker into two! His body crashes behind me lifeless until Heracles annoying revival ability kicks in bringing him back to life.

Zi-O: !

I blocked his strike and launched me in the air.

Heracles instantly appeared in front of me ready to slash me once more. Didn't bother giving him that chance by using my time ability to turn his Axe-Sword into dust! Grab Heracles face tosses him down while I follow suit. Have both hands together smacked him hard onto the ground that created a crater. I am slowly descending back down as Berserker got back up. Roars in anger. I can't help but be bad for him. But hey, if I die here then it's all over. No do-overs. I'll become stronger no matter what. I will surpass every so-called god. Summon a couple of Kamen Riders to fight against Berserker.

Kuuga!

Hibiki!

Decade!

Wizard!

Zi-O: Go!

The battle commenced as four Riders dashed towards Berserker. Heroic Spirit moves fast speeds to land a strong punch at Kuuga Ultimate except Kuuga blocks Heracles right fist with his left punch. Next he energizes his right fist for a powerful punch that obliterates Berserker. Again he revived except he was slashed into two by Hibiki Armed. Came back to life again, went for a kick at Decade. Passing Through Kamen Rider jumps high then activates his finisher.

Final AttackRide: D-D-D-DECADE!

Holographic cards with his emblem materialize in front of him. Goes through it increases his speed and attack as Decade landed a Rider Kick killing Berserker. He backed away while Berserker revived himself which was short live after Wizard took him down with his own Rider Kick. The four Riders vanish, I move extreme speeds of speed type Riders and my own super speed and punch hard on Berserker's face sends him across the forest. I've reappeared behind Heracles kicking up him high at the skies. Summons OOO, W, Fourze and Kiva in their final forms take a shot at killing Heracles. Revive while falling down landed on his feet. I've gotten bored already. Didn't bother to move, Berserker just came at me for a tackle attack. Use Time Freeze to freeze him in place. Tap Faiz statue to summon Faiz Blaster weapon in Blaster moves. Press the trigger firing a powerful blast killing him. Unfreeze Heracles as he revived again. Tap Ex-Aid for Ex-Aid Muteki finisher landed multiple kicks that dealt critical damage. Came back one more time, I activated my finisher.

Finish Time! King Advent All-20 Time Break!

Zi-O: Toooria!

*Boom sfx*

Level Up!

Soren Azure lvl.120

I landed on my feet and De-Henshin to normal.

Soren: Now....he should be at the temple. Time to put that arrogant asshole in his place. I'll do it as fast as possible. And I know which one that'll help me dodge many of his weapons not even he can keep up.

I look into my equipment to see my armor that'll drastically increase my speed. The speed of a God.

Soren: I better take him down before he unleashes his powerful weapon or I'm toast.
