During the final battle against Arjuna Alter, Chaldea's group is slowly being overpowered by the Final Black God, until they are aided by one unlikely ally.


Karna was pushed to the ground by Arjuna Alter's attacks, as the god looked down on him before launching one more strike, which Mash jumped on the way to block.

Despite his augmented power, they still weren't powerful enough to beat the Lostbelt King after he was powered by the Fantasy Tree Spiral. Arjuna's constant energy attacks made both a powerful defense and a mighty attack.

"Your anhilation has come Karna. You are all that comes between me and my perfect world" - the god spoke as he prepared to fire Gandiva.

Their Master, Ritsuka, watched everything, feeling powerless. He knew that he would be next, yet he could do nothing to help his Servants against this almighty foe. As he looked at what seemed to be Karna's final moments, everything around him froze, and turned to a gray color.

"Hey, don't look so down, or do you have no trust on them?" - a voice asked from behind the boy. As he turned to look, he saw a tall and muscular man with no shirt, light green hair tied backwards in a classic way with what seemed to be a golden crown. He also wore a pair of rectangular glassess.

"Who are you?" - Ritsuka asked.

"Call me Buddha, I came here after seeing your fight with the other god, Arjuna was it?" -

Fujimaru was confused as to why the man was there. Xuanzang had told them that Buddha preferred to not get involved in man's business, even during the Incineration of Humanity or the Bleaching of Earth.

"Well, whatever his name is, it seems like you're in quite a problem against him. Don't worry though, I should be able to help" -

"Help? How would you..." -

"By merging together with you. What did you call that process? Pseudo Servant...? Well, whatever the name is, pretty sure by doing it you'll stand a better chance against him" -

Ritsuka thought of it for a few seconds, not sure if such a thing would work, but if it gave them a better chance to beat Arjuna Alter, he had to try it.

"If it help us, I'm willing to do it" -

"That's what I like to hear. Now, come on Ritsuka Fujimaru, be blessed with my power, even if for this fight alone. You and I shall fight as one" -

Ritsuka and Buddha held hands, being enveloped in a golden bright light. With that, time returned to normal.

Gandiva fired straight at Karna, but as the attack conected, something jumped in front of it to block it, creating a massive cloud of dust.

"Whew, that was a close one, good thing I made it in time" -

"That voice... Master!?" -

"Senpai!?" -

After the dust cleared up, one person stood, holding The Shield To Destroy The Seven Misfortunes thanks to Fourth Realm: Asura Realm, Eleven Faced Kannon - Ahimsa. It was Ritsuka, yet at the same time, he was different.

Instead of his usual black and short spiky hair, he now sported long black hair all the way to his waste. His muscles seemed to have increased a little bit as well.

"Hey-o, Mash, Karna" - he said, while not moving the shield - "Hold on please, this will take only a moment" -

In a second, he turned the shield into the Indestructible Varja Short Sword using Second Realm: Human Realm, Unshakeable Cord Kannon - Akshaya, before unleashing a powerful slash towards Arjuna Alter. While the strike didn't conected with the god, it managed to push him back.

"You... You shouldn't be here, you don't belong here" - Arjuna Alter spoke in a calm yet menacing tone.

"Last time I checked, neither should you, yet here you are anyways, so there shouldn't be a problem if I take the spotlight for a few minutes" -

"Hmph. No issue, you as all others who may be evil, shall be cleansed from this world and-" -

"Shaddap" -

"... What?" -

"I said shaddap, I don't care about what you have to say" - he said, as he changed the sword back into a giant staff called Six Realms Staff - "I was summoned here to protect humanity, and that's exactly what I plan on doing" -

"Senpai?... Are you there?" - Mash said in a weak way.

"Oh right, should've introduced myself. My name is Buddha, Saver Class, and a god that wishes to protect mankind! This boy allowed me to share his body to aid you against him, you can call us... Buddhamaru! Now, Arjuna Chan, ready to start this battle for the ages?" -

Arjuna Alter fell silent, he could not process why such a deity would be in his Lostbelt. Meanwhile, Karna and Mash slowly approached Ritsuka.

"Master, are you alright there?" - Karna asked.

"I'm fine, just sharing my body with a god right now. Now, what about we teach Arjuna Chan a lesson?" -

"Arjuna... Chan?" -

"My personality and Buddha's got mixed up, don't think too much about it. Now, let's get this party started!" -

While the sudden merging confused both Servants, with one look they knew that even with a god inside, their Master was still there, and they were ready to join the battle.

Karna took to the skies and used his spear to slash Arjuna Alter, attack which his enemy managed to block, but left himself open to a strike from the back from Ritsuka.

With this attack, they were able to stun the enemy god, allowing Buddhamaru to start setting up his first Noble Phantasm: Chakravatin. Turner of the Wheel.

"This should give us enough of an advantage to get this done quickly" - he said, as the giant chakram started to fire rounds of light against Arjuna Alter, further weakening the Lostbelt King.

Mash, using the propulsors on Ortinax, launched herself against the god and managed to strike it in the face while Karna attacked from fireballs, distracting him from Ritsuka, who used First Realm: Divine Realm, Wish Granting Wheel Kannon - Lokapala to turn the Staff into the Twelve Deva Axe to slash him across the face, nearly cutting one of his eyes clean off.

"Bunker Bolt, increasing Ortinax performance, now!" - Mash yelled as she powered herself up, using this extra energy to hit Arjuna Alter so hard he went flying to one of the rocks nearby.

Ring 1, completed.

The Chakravatin never stopped firing at Arjuna Alter, even after he had alredy fallen, yet the god still had quite a bit of fight in him and wasn't going to go down this easy. From the spheres that surrounded his body, he fired several blasts of energy that managed to put all of them in guard.

"He's tough" - said Karna while standing behind Mash's shield.

"Fitting for a Lostbelt King, but no problem, all we need is to stall enough time" - said Buddhamaru.

"Stall? Senpai, we need to..." -

"Take him down as fast as possible, yes. However, I have 1 trick up my sleeve, but I need all of the 7 rings of Chakravatin to be completed. If we can keep him busy for long enough, we'll win this" -

Both Servants simply nodded their heads as Arjuna Alter started to increase the intensity of his lasers.

At incredible speed, Karna managed to slash his enemy before kicking him away and attacking once more with his fireballs.

"Hey Mash, how about a double shield bash?" - Buddhamaru asked.

"Y-Yes!" -

Using the Shield that Destroys the Seven Misfortunes and together with Mash using Bunker Bolt, both started to hit Arjuna Alter again and again using their shield. Left, right, up, down, their coordinated movements allowed them to evade the Lostbelt King's attacks before Buddhamaru used Third Realm: Animal Realm, Horse-Faced Kannon - Nirvana to turn the Shield into the Giant Spiked Club and bashed Arjuna's head directly with it.

Not wasting even a single moment, Karna appeared behind him and, with a spear charged with fire, landed a powerful strike on the god.

Ring 2, completed.

"This power... Even after transforming... It feels unreal" -

"You noticed it too Karna San? Ever since we started fighting with Senpai..." -

"That's one of Buddha's skills, he calls it Common Destiny. I don't exactly know what it does, but according to him it's a boost in power for you guys now that we're summoned, quite handy if you ask me" -

While the three talked calmly, they noticed Arjuna slowly getting up as he prepared his counter attack.

"You cannot defeat me, I am the perfect god!" - as he said that, a barrage of energy beams were shot at all of them, with them barely being able to summon their defenses in time to block it.

"I'm going in. Master, please strengthen me" - Karna said as he looked at Buddhamaru.

"Right, here you go!" - with that, a Command Seal was used and Karna felt the energy flowing through his body, the mana was overflowing and had to be let out, and he did so in the most destructive way he could.

Going to the skies, he prepared to use his Noble Phantasm, which Arjuna Alter prepared to block, only for him to be stopped by a wave of hits from Mash and Buddhamaru.

"Take this!" - Buddhamaru slashed him in the eye with the Indestructible Vajra Sword.

"And this!" - Mash hitted him in the chest with her shield before activating her propulsors and launching herself up, hitting his head as well.

"You both... ENOUGH!" -

"VASAVI SHAKTI!" - as Arjuna Alter pushed both away, the full strength of Karna's Noble Phantasm landed directly on his face, creating a huge crater in the area.

"Very well then, if we can continue like this it shouldn't take much to take him down" - Buddhamaru said.

Ring 3, completed.

From the crater, Arjuna got up slowly as the rest looked, ready to continue fighting.

"Ultra-Synthesised Deity, so that's how he's taking so many blows and not going down" - Buddhamaru prepared his Varja Short Sword.

"Do not worry Master, Shiva and Vishnu's Blessings will protect me" -

"Ortinax is at maximum performance, I can keep going with no problem Senpai!" -

"The power of an Omni Divinity... None of you can match it!" - Arjuna Alter's power suddenly increased. His frst move was to summon a ring of energy and fire it towards Karna, who blocked it yet was pushed back because of this attack.

The next were Mash and Buddhamaru, both of which were attacked by several energy beams, forcing them to go into a defensive position with their shields.

"You hold the power of the Buddha, but if you believe this will help you in anything, you're severely mistaken" -

"Don't know much about that, you should never get cocky, even if you're... A God!" -

Arjuna did nothing but increase the intensity of the attacks, pushing Buddhamaru back but weaking the attack at Mash. Seeing this, the girl jumped at him and slammed her shield in his head, distracting him for a moment.

Using this helpful moment, Buddhamaru got the chance to push Arjuna Alter away and summoned the Twelve Deva Axe, slashing the Alter in the chest and kicking him away.

This was answered with a pillar of light directly from the heavens that managed to get a direct hit in as Arjuna Alter created a giant explosion where Mash was, damaging her and sending her flying.

After being knocked back, Karna returned, with high speed slashes that managed to wound the God before attacking with fireballs and ending with a powerful strike to the chest, which unluckily for him was dodged.

"You die today Karna" - with a soft whisper to his face, Arjuna Alter fired the same pillar of light on top of his long time rival, but Karna moved just at the right time to dodge the hit.

Ring 4, completed.

As Arjuna Alter moved for a second hit, the Chakravatin wheel started to fire onto him once more, damaging him a bit and allowing Karna to recover his strength.

"I will end you righ here!" -

"Won't allow it!"

Both of them fired energy lasers at each other, colliding as they fought to see who would come out on top, but before they could continue Mash got up and utilizing Bunker Bolt launched Arjuna Alter towards a rock.

"This bastard, he focused a lot of energy in that attack... Dammit" - Buddhamaru said as he slowly approached, his left arm burned from Aruna Alter's attacks.

"Senpai, are you..!?" -

"I'm fine Mash, Buddha's powers protect from, and I'll heal from this but... No, we can take him on, we just need to defend until the 7 rings are finished. Mash, we'll need your Noble Phantasm, I'll power you up" -

"Right, allow me Senpai!" -

Using his second Command Seal, Mash's energy increased and with that, she was able to summon a more powerful version of her Mold Camelot. Now, with their defenses set up, it came down to how well Buddhamaru and Karma could keep Arjuna Alter at bay.

"I'll fight him directly, wait for the moment and then we'll strike him down, understood?" -

"Understood" -

"Great. Now, both of you, wish me luck" -

Ring 5, completed.

Stepping outside the defenses, Buddhamaru summoned his staff once more, yet this time changing it into a giant scythe with the head of a lion, the final form of the staff, called "Fifth Realm: Preta Realm, Holy Kannon - Salakayas".

"Like it Alter? This is the Scythe of the Wild God. Seems like Buddha seriously wants me to take you down, so by all means" -

"Even with that weapon, your power pale in comparasion to mine, you cannot win" -

"Alredy faced overwhelming odds before, always overcame then, you won't be any different mister Final Dark God" -

Preparing the scythe, Buddhamaru launched a forward strike which Arjuna Alter blocked with his energy spheres.

"Not bad, but this is just getting started" -

Chakravatin started to fire once more, with several shots landing directly on Arjuna Alter, weakening him and allowing Buddhamaru to slash him directly with the Scythe, following it up with a kick to the face and a punch in the stomach, knocking the Alter back.

Seeing this, Arjuna Alter stopped going for energy attacks and instead punched Buddhamaru directly in the face before kicking him in the chest, headbutting him and then punching him again, throwing him into the ground.

The Pseudo got up after that and grabbed once more the scythe. The lion's head started to emit a powerful flame which propelled it forward, cutting deep into Arjuna Alter's arm and nearly ripping it off.

"Now we're settled, right?" -

The god looked at the Pseudo in anger and prepared to strike once more, but was stopped by the a spear launched directly at him which pierced his chest before he was kicked by Karna.

Ring 6, completed.

"That worked out better than I expected" - Buddhamaru said while holding the scythe over his head.

"He's finally down for good..." - Karna said as he looked at Arjuna Alter, yet the Final Dark God wasn't going to go out with such ease.

His body started to glow in blue andhis arm regenerated, as he had activated the skill 'Lamplight of the Soul: EX'.

"Saṃsāra of Genesis and Terminus. Give life to those who are good, judge those who are evil" -

Soon, Buddhamaru and Karna noticed that they no longer were in the Tree, but rather floating in space.

"This is going to hurt... Karna, behind me!" - Buddhamaru yelled as he summoned the Shield that Destroys the Seven Misfortunes.

"Activate, sword of recursion, so that they may perish. MAHAPRALAYA!" -

The sword fell and the explosion enveloped their bodies before returning to the Tree. Arjuna Alter slowly descended onto land where Mash awaited him, staring at the cloud of smoke that was created because of the attack.

Once it went away, there were Buddhamaru and Karna. The first one was heavily damaged by the attack, but breathing, while Karna was standing up, having been protected by his Master.

Both him and Mash looked at Arjuna Alter, he was weakened from the fight, and they could finish him off.

Without thinking wtice, they launched themselves at Arjuna Alter, with Mash directly hitting him with her shield while he recieved a strike from Karna in the back before being blasted by fireballs.

Powering up with Bunker Bolt, she struck with great force and sent the weakened Arjuna Alter flying back before Karna, at great speed, slashed him several times and finished with a beam of red energy.

Ring 7, completed.

"Alright, it's done... Karna, Mash, step back" - Buddhamaru said as he slowly got up from the ground - "The wheel tells time. All lives and all anguish shall return unto me. Under the great Enlightenment, humanity shall become one, 'Amita Amitābha'!" -

From the Chakravatin, multiple beams of light came and struck Arjuna Alter directly, a Noble Phantasm that hit with the power of human history, yet... There wasn't any human history in the Lostbelt due to the multiple resets.

Despite the power it would have in Pan Human History, in the Lostbelt the attack was greatly weakened. Arjuna Alter, after tanking the full blow of it, walked away covered in smoke and wounds, yet still standing.

"I don't have words to express how that makes me feel" - Buddhamaru said. He looked at his hand, and saw that he still had 1 more Command Seal up.

"You fought valiantly, yet for naught. Once the world resets, you will be erased from the perfect world" -

"Heh... You really think you won? There's still 1 more trick... Karna, by my Command Seal, unleash your Noble Phantasm without holding back!" -

Raising his hand while the last Seal dissapeared, Karna flew to the skies while emiting powerful flames.

"Watch, Indra! I will burn it all! Vasavi Shakti!" -

The Noble Phantasm got a direct hit, leaving the battlefield in silence after Arjuna Alter vanished from the hit.

After that, Buddhamaru approached his Servant and, in a second, Ritsuka fell to the ground while Buddha stood behind him.

"The boy took a lot of punishment in that fight, make sure to treat him well" -

"You were the one who aided Senpai during the fight?" -

"The one and only. After seeing what you were going through, I needed to help, yet I couldn't on my own, my only way was to bond with him" -

"Whatever the case, we appreciate what you did for our Master, and thanks for helping us defeat the Lostbelt King" -

"No problem. Well, this is where I take my leave, I'll leave the rest up to you" - Buddha said as he started to dissapear.

"Will we see you again?" - Mash asked.

"Maybe, maybe not. Ask your Master after you return to safety. Now, it was a pleasure working alongside you Chaldea, see ya!" -

With those words, Buddha dissapeared and Ritsuka woke up. Chaldea would now need to destroy the Tree itself...


Chaldea vs Arjuna Alter.

Victor: Chaldea.

Match Length: 12 minutes and 45 seconds.

/A few days later/

After solving the crisis of Lostbelt 4, Ritsuka and Mash were now in the Summoning Room, getting ready to summon those they met in the Lostbelt. After using the Saint Quartz, ranbow sparks flew from the machine before a blinding light covered them all.

"Hey, you're the Master that I helped! Well, it seems I'll lend you my power more directly now. Saver, Buddha, I'll be in your care from now on" - a voice said through the smoke.
