Chella and Evaline climb back up to the crystal field thanks to using the shards found in the chamber that Evaline hibernated in. They look around and see no monsters around. Looking further, they see the monsters gathering around the castle.
Unsure of what's going on, Chella goes ahead and scouts. She sees a lot of monsters ahead. If they can't fight then they won't be able to pass but Evaline seems to have unlocked the power in her. They charge ahead through the horde with Evaline on the front after creating a path separating the monsters.
"Your crystal power is awesome!"
"I'm just being helpful is all."
"By the way, do you think there's anything inside the castle?"
"I could sense it. The sultan...the monster behind all of this. We have to destroy it so my people could finally rest."
"I can't agree more. We'll defeat that thing and find my friends."
After passing through the horde of monsters, they break into the castle. Evaline feels nostalgic as she looks at the familiar spaces but ruined for years, even her bedroom. Chella gives a quick admiration of the castle while Evaline readies herself to bid farewell to this land. Both of them approach a big door in a hallway, suspecting that their enemy is on the other side.
"Are you ready to end this?"
"...yes. I shall create a peaceful end to the story that my parents cherished so much."
"Let's go."
Chella opens the door only to see the sight of Nova, Gilbert and a girl she doesn't know lying on the ground, injured. Evaline seems a large figure coated in crystals sitting on its throne. She knows it when she feels the malice contained inside the impenetrable vessel.
"Edmont, you traitor..."
"I knew you had been alive all along, princess. Your body was never found but I never expected you to be able to due anything against me. And now you're here."
"You'll pay for your treason."
"You might be able to pass my underlings, but I'm on a whole different level. Doesn't matter how any friends you bring, I'll crush them not after I drain their blood of course. It's been so long after all."
Evaline forms crystal gauntlets on her arms and punches him but true to his word, he simply blocks it with a gesture. He knocks her away from his throne. Her body collides with the wall and falls. Evaline tries to get herself together and stands up. Chella tries to land a hit with her hips only to be grabbed by the crystal king and thrown away.
"See? None of you could match my level. Here I was hoping to have some fun with you before consuming you, but oh well."
"I'm not done yet."
Evaline throws crystal-like projectiles as him but he creates a wall made of crystal to block them. She coats her fists in crystal then leaps in order to launch an all-out attack on him. He responds with his knuckles. The 2 of them keeps pushing each other with their attack. Chella notices a crystal sphere shooting laser at Evaline, telling her to dodge it. Evaline jumps backward to dodge the laser.
"You puny humans won't able to survive the next move."
"What?"
The crystal king spawns crystals shards everywhere in the room then shoots a laser beam from his finger which the shards deflect, making it travel almost every where. Chella and Evaline receive multiple hits from the attack and can barely stand. The group are overwhelmed by his laser attacks. Evaline feels her inability once again, she wishes that she could've been stronger not to let others down. Panda decides to suggest something that could give them a winning chance.
"You with the blonde hair, can you create a crystalized weapon?"
"Yes, but what are you intending to do?"
"If you want to be a knight, a sword and a shield are necessary to have."
At Panda's suggestion, Evaline creates a saber and a shield out of thin air. Panda stands up and touches them with her palms. Meanwhile, Nova and Gilbert tries to gather their strength to stand up. Chella approaches them to see if they're alright. Evaline doesn't get it but Panda tells her to tries the forged gear regardless.
At the moment, the crystal king recalls that earlier Panda was able to shatter his crystal walls in an instant. He has never seen someone with averarge body size yet could deal so much damage. He had to use ranged attacks to would her. Now his opponents are doing something questionable but his power level is still way higher. He doesn't need to worry about the remnant of the past.
"The princess wants to slay the monster herself? Then come at me, if you can."
"You won't be able to stay confidence once you see the might of the weapons I forged for her."
Evaline dashes forward, aiming for the crystal king. He creates a thick wall to prevent her from reaching him but she bashes through with her shield. The wall is destroyed, which surprises him. The crystals he rules over should be impenetrable considering that his power level is higher than the deceased king. The battle seems to lean on Evaline's side even though she's confused about it. With the hope her deceased parents have given to her and the aid of her new companions, she vows in her mind to win.
The crystal king creates a huge laser beam, Evaline blocks it with her shield to protect those behind her but the impact pushes all of them backward and they fall off the castle. Panda grabs on the rope she used her earlier and swings herself to catch the others, thanks to that they land safely. The monster king himself jumps off the castle and morphs into his phase 2 form which is twice bigger and the crystals on his body have a darker glow. In this phase his mind is nothing but feral, truly becoming a monster like he always is.
"What the heck? Phase 2? What are we going to do now?"
"Don't fret, Noelle. I'm sure we could come up with something."
"If only Bit was here, instead of having to maintain the Driller."
Nova notices something approaching from afar. Looking closely, it's a huge drill. Gilbert is surprised that Bit could find them even this deep underground. As the vehicle gets close to where the group are, the watch on Chella's wrist activates on its own.
"Chella, I've come to assist. It seems like you are dealing with a high-level threat."
"Chella, let my drive this time."
"Sure thing, Nova."
Gilbert gets inside the vehicle along with his granddaughter. Both of them ready to assist in the phase 2 battle. Chella approaches Panda and Evaline, wanting to help as well. Panda takes out a pair of tonfas to give Chella, she tells her to use them. Panda herself will use an iron staff to fight. With weapons in hands, the 3 girls continues the battle.
The monster king's roar attract the monsters far away and they all gather around the area. Evaline fights the king and the rest will fight his lackey. The horde of monsters are coming at Chella and Panda, they ready their stance. 3 of the monsters jump from behind Panda but she swings her staff backward and break all of them to pieces. Chella kills a monster by knocking right into its torso. The battle is tense with the human team fighting so hard despite the disadvantage in number.
Nova is currently piloting the vehicle and crushing some monsters with the front drill. There are still lots of others in the surrounding but it won't be a problem for the driller itself. Meanwhile, the monster king and Evaline have a confrontation. He shoots a big laser beam from his mouth and she tries to get away from it. He then stomps the ground, generating crystal shockwaves spreading in all directions. Evaline could barely block it off but she doesn't stop there, she leaps forward slices off his right leg which causes him to fall over.
"Finally..."
"Gaaaaaaaaaaahhhhhhhhhh!!!!"
"This isn't over, I know. I need to make sure no traces of will be left on this land so your malice will never stain it again."
*growls*
His severed limb regenerates as he morphs into an enormous crystal sphere and rolls like a ball. Evaline barely dodges it but it doesn't stop. It rolls in Nova's direction, crushing the grunting monsters and knocking the Omega-Driller away. Nova and her grandfather once again experiences the dizziness caused by a huge impact. But they quickly recover after a bit. She begins charging the conducting handle with her hands, preparing to use the canon.
When the rolling sphere is approaching Chella and Panda, Panda shatters the ground with a stomp thus creating a sinkhole to stop the rolling sphere from its track. Chella takes down some monsters by spinning her body with the tonfas. Yet, more monsters are coming and their king is yet to be defeated. The battle has yet to end.
