The Fatebreakers entered the next room, leading to an area called the Proving Grounds.

"Only one more area to go until we reach you, Fontaine. I hope you're listening." Tanya said.

"It sure has been a long road, kids. Longer with Johnny. He wasn't even born when I bought him off his mom." Fontaine said. "But all good things gotta come to an end. It's been a good run, but you all ain't seeing the surface again."

"Big words from a guy on the radio." Kazuma countered.

The group carried on through the grounds, until they heard a loud roar echo throughout the grounds.

"Oh yeah, I forgot to mention: that L freak is lurkin' around here." Fontaine said casually. "Have fun with him."

"Well… it was bound to happen eventually." Ethox said. "These hallways are too small for him. Doc, where would L be in this place?"

"The most likely area would be the Central Atrium." Tenenbaum hypothesized. "As urgent as the threat of Fontaine is, L must be stopped as well, before he causes the way forward to be destroyed. Go, and put him to rest."

"Right. Let's go." Mirror Match agreed as the group pressed forward, making their way to the large, open, Central Atrium, full of museum exhibits. On top of a large whale skeleton, the group witnessed L's monstrous form tearing a Rosie to pieces with its tentacles.

"And there, the tragic monster lies…" Necroapache said. "Let us relieve it of its burdens."

L then noticed the group, and with a screech, leaped at the group, crashing down on the walkway in front of them, roaring.

"I would say good luck with that freak, kids… but let's be honest. You ain't got a chance in Hell." Fontaine said.

(Cue: Monster- Skillet)

Dark Ocean Sub-Leader; Raging Leviathan of Destruction

L

The monster lashed out with its tentacles, lashing them at the group.

"Look out!" Ethox said as everyone dodged, L's tentacles damaging everything in sight.

"These attacks are completely erratic!" Gimilor said. "In that state, L can't control himself!"

"Then we control for him!" Molotok decided as he entered Origin Beast Mode and grabbed one of the tentacles, holding on as it whipped around in the air, even keeping grip when he was slammed into a wall. With a roar, the hammerhead Beastman ripped the appendage off, the wound spewing out black, blood-like liquid.

"Alright then! Everyone, get rid of those tentacles!" Ethox ordered, slicing another one of them off.

Goblin Slayer narrowly avoided a tentacle crashing down onto him, quickly turning around and severing it from the monster.

Seiya was focused as several tentacles converged on him and Rista, quickly and expertly chopping them to pieces with Eternal Sword.

"Ma'am, there's too many of these tentacles!" Grantz called out as he took out on with a piercing spell. "At this rate, we'll be overwhelmed!"

"Then let me handle it and stop panicking!" Tanya yelled as she looked to L, pointed her rifle, and uttered a familiar prayer. "Lord, hear my humble prayer, I have humble need for your miracles. Swing your heavenly sword, so that they may taste divine judgment."

Tanya fired a bullet that multiplied in the air, destroying the remaining tentacles all at once. L shrieked in pain as he started to thrash around in an attempt to crush the group.

"We need to end this." Ethox said as he raced forward towards the monster, Keyblade in hand. "Unparalleled Eastern Arts!"

Ethox went for the final strike. In that moment, in slo-mo, he could hear L call out to him, inside the body of the monster.

"I҉̨̛t̀ ̷͏h̢͜͢͡u̢͘͡r̴͞t̡͏̵̢͝ş̢͢.̧͟.̶̛͢.̵̸̢" the voice of L said. "M̷͜á̴͘͠k̵͜è̀ ̧́͞i̡͡͏t͏̶̵ ̵̕͏̵e͟͟n̸̷̢̕̕d̢̀.̢͘͢͞.̶̢̕.̢̀͢͜"

With an expression of sad acceptance, Ethox connected a new attack, slashing the monster L had become.

"...Tainted Soul Liberation."

(End Song)

The monster's screams grew silent as it collapsed, before it slowly began to shrink and morph, returning to L's human form, which looked weak, malnourished and tired.

"T͡h̨e ̵̢̨pá̧̛in.̡͝.̀͟.̴͞i̷s͝ ͞f̨͞ąd̴̵i̶̕n̕͟͟g͡.̷̵҉.͝.͠" L croaked out as he laid on the floor, as his body began to divide into two streams. "͜A̢͟t̵̶̨ ͜l͝͝a̛s̀t́.̢̀͟..m҉̴͜y̢̧ ̕l̶͠į̴f̕͜e͡ ̴į̧͟s̀ ҉o͞v̨͏e̵̡͢r̀.̵͠.̸.̸"

"...We're sorry it had to end this way." Michiru spoke up.

"̕̕E̴ve̵ŕ͢ ̵̡s̴̛͟i̛nc̷͘͝e͝ ̨t͡h̨a͏͢t̕͘ ͝d͘a͡y̷̕͜,̶̧ ͏t̵ḩe ͢d́́ay͠͠ ̀͏I̶ ̨̨was ͠͠m̛͡a̸d̴e ̡͝a̢͘͟ ̨́mo̧͡nst҉e͞r.͘..̷͠I̡ h́av͠e b҉ee͢n̷ a̛n ou͝t͟s͘ider,͢ ͢a ̀s̨trang̷e̸r ̛ìn ͏t̵his ̶cen͜t̨ur͜y an̴d ̴a̵m͟on͞g ͜t͟hose͠ w̷ho a̷re s̷til͠l̵ m͟en̛.̷" L said, not looking at the group, as if his mind was somewhere else. "At ̨l͏o̶ng ̵l̸ast...͟I ͞ám f͘re҉e.́.."

"Thank you."

Those were L's last words as he faded away completely, the two streams converging into a floating Dao symbol. With the ring of a gong, the symbol faded away, leaving the grounds silent.

"Go in peace, and…may you rest eternally." Ethox said quietly.

The group stood in silence for a moment, before Tanya spoke up.

"We're done here. Let's go get Fontaine." Tanya urged the group.

And so, they carried on, knowing that they had done the right thing, but still with a heavy feeling in their hearts.

In the final location, a lab…

Fontaine slammed his fist on a wall.

"Dammit! I was bettin' everything on that freak! Now there's nothin' between them and shuttin' down this city!" Fontaine said. "Well it ain't over yet!"

He went to a machine in the lab, likely purposed for splicing.

"They wanna take me down so badly? I'll give 'em a fight they ain't never had in their lives! I'm gonna splice myself with ADAM until there ain't nothin' left to splice with!"

Fontaine then activated the machine and hooked himself up to it, multiple needles injecting into him as he screamed, ADAM pumping into his body.

However, Fontaine didn't notice the shadowy mist coming down from the rafters and entering the tubes carrying ADAM into him, the green liquid turning black…

"Aug…AAAHHH! OH YEAH, WOO! THAT'S WHAT I'M TALKIN' ABOUT… I WANT EVERY LAST DROP!" Fontaine yelled as his body started to be covered in darkness…
