Hellen hummed a tune as she watched cartoons in bed, eating some snacks she ordered from room service. Humans sure have come a long way, even without the use of magic. Splitting atoms, going to the moon, even eradicating a virus. In all honesty, she never thought they would achieve so much. Her thoughts were interrupted by the sound of the door knocking. "Who is it?"

"Room service!"

Hellen quickly put on her hood and adjusted it so only the good side of her face was shown. "Coming!"

After receiving her food and giving the bellhop his tip, Hellen returned to the couch and continued watching TV. But as she settled down, she couldn't help but feel like she was being watched, and she glanced out the window.

On a rooftop across the Grand Paris hotel, Ladybug and Chat Noir ducked their heads. "She saw us," said Ladybug.

"I don't get it," said Chat Noir. "Are you sure that's who you say she is?"

"Oh, yeah, that's definitely Hel, Loki's daughter! She's here for the Mask, and if she gets her hands on it-"

"Watcha doin'?" asked Big-Head, popping up between the two of them, making them scream. "Ooh, are you spying on someone? Are they pretty?"

"It's none of your business," snapped Ladybug.

"Actually, it kind of is," pointed out Chat Noir. "It does involve his Mask, after all."

"My Mask?" asked Big-Head, genuinely confused.

Ladybug exhaled, then said, "Fine. As long as he doesn't do anything crazy." She turned to Big-Head and said, "There's a..." She tried to find the right words. "...a goddess disguised as a human who wants that Mask..." She tapped him on the head. "...you're wearing."

"Touch me again and I'll conk you. Why does she want my gorgeous looks?"

"We believe it's Hel, Loki's daughter," said Chat Noir.

A sneer formed on Big-Head's face. "Interesting. Maybe I should..."

NO! Don't go anywhere near her!

"Shut up! This is my body! I can do whatever I want!"

No! It's MY body! You're just a Mask! I can rip you off and expose my secret identity to these two!

"Are you sure you want that, kid? You know you will be arrested on the spot as soon as I come off!"

I don't care!

Ladybug and Chat Noir glanced at each other. "Is he arguing with himself again?" the latter asked.

Big-Head shook his head and said, "You know what, I'll cut you some slack and listen to you just this once. Though, it would have been nice to give a goddess a wedgie."

"Glad we're on the same page," said Ladybug. "Kind of."

"Eh, I'll let you get on with your peepshow," said Big-Head as he turned to leave. "What you do with a goddess is your business after all." Still, there was a nagging feeling in the back Big-Head's mind that told him he should go into the hotel.

The next morning at school, Juleka returned to school from the hospital, much to the delight of everyone, save for Chloe. She no longer looked like a skeleton anymore, but she still looked pretty thin. "Juleka," said Rose as she gave her a hug. "How are you feeling?"

"A little better," said Juleka as she returned to her desk. "But I've got a very hefty appetite. Being reduced to skin and bones would do that to you."

"I still can't believe that woman would do that to you," said Nino. "I saw the footage on the news! One tap with that knife and she emaciated you!"

Juleka shuddered. "Please, don't remind me. The hunger I felt after that was unbearable. I had to eat slowly, and gain my nutrients through an IV tube at the hospital."

"That's good," said Max Kante. "Eating too much too fast can cause re-feeding syndrome."

Juleka held up her hand. "Please, don't say feed."

"She's right," said Miss Bustier. "We must return to our studies. Leave Juleka alone."

And like that, class returned to normal. Alya leaned in and whispered, "Did you get a good look at the woman's face?"

"I did," Juleka whispered back. "I think she's the woman living in Chloe's hotel. One half of her face was pretty, but the other half was withered, like a corpse." She shuddered again. "Please, I don't want to talk about it."

Where have I heard that before, Alya thought. She looked at the history on her phone. Specifically, the parts about the Mask of Loki. Sure enough, she found what she was looking for. She had to talk to Marinette and Rudi about this.

After school, Alya met with Marinette and Max under the bleachers. "The daughter of Loki," Marinette asked. "Are you sure?" Of course, she already knew since she is Ladybug, but she had to keep pretending.

"Yes," said Alya. "The powers of freezing cold and famine, the disfigured half face, the fact that her name is Hellen...it's definitely Hel, the goddess of the underworld, Helheim."

Rudi face palmed. "Great, so we're dealing with a literal goddess now? Why is she here anyway?"

"Isn't it obvious," asked Alya. "She wants her father's Mask! We have to warn Ladybug about this."

Marinette said, almost too quickly, "Ah! That won't be necessary. I think Ladybug is already investigating it. No need to worry."

Rudi said skeptically, "If you say so."

Some time later, Lt. Kellaway was in the park, apparently having gotten a text message from Ladybug, something about the Mask. He didn't have to wait long as she swung down in front of him. "You wanted to see me, Marin-"

"Shh!" Ladybug looked around.

"Relax," Kellaway said. "No one's around."

"You can't be sure. You're already in danger just being here! If Hawk Moth akumatizes you, you'll tell him right away that I'm Ladybug!"

"You'd be surprised how strong my will is. Anyway, you said you had something you wanted to share with me?"

"Right. Well, it turns out the whole Mask situation has gotten worse. Loki's daughter, Hel, is in Paris and she wants her father's Mask bad!"

"Who is Hel?"

"The goddess of the underworld in Norse mythology."

Kellaway stared, then facepalmed. "A goddess. Just when I thought things couldn't get any worse. What do you want me to do?"

"At this point, nothing. Trust me, I've seen what she could do. She can control snow, and famine."

"Famine?"

"Yeah. I saw her make one of my friends so thin, you could see her skeleton poking through her skin! Lieutenant, I think it might be best if you leave the Mask to me and Chat Noir. Besides, if Hawk Moth finds out you know our secret identities, he'll never stop sending akumatized villains after you."

"Sorry, Lieutenant. Gotta bug out!" And with that, Ladybug swung off.

Kellaway let out a grunt of frustration. "I wish I could do more!"

The circular window to Hawk Moth's lair opened and butterflies swarmed around him. "Anger and frustration, a perfect feast for my akumas." He grabbed one of the butterflies turned it from white to purple and let it fly out the window. "Fly away my little akuma, and evilize him!"

Kellaway looked up and saw the butterfly coming toward him. "Oh, no, you're not going to change me! Happy thoughts, think happy thoughts. Toys in Christmas, sleigh bells, snow, Neverland, Peter Pan..." To his amazement, it worked as the butterfly moved away from him. "Whew. Maybe Ladybug was right. I probably shouldn't get involved in this."

Hawk Moth growled, "No! The anger is disappearing!" Then he smiled. "Ah, but I sense another stronger source of anger somewhere."

Hellen was walking down the streets, admiring the city's architecture. She decided to visit the Lourve for the time being and take a look at the humans' artwork. The sound of explosions made her look in the opposite direction. "What in Helheim?" A large figure landed across the street. It looked like a man with gray skin, unkempt red hair, a massive body and a pot belly, and wearing shredded clothes. The creature saw some tourists, then bounded over to them, making the ground shake. He picked a woman up and roared, before he spoke in a deep voice, "You are so ugly, that when you were born, your doctor slapped your mama. HAW-HAW!" There was a tremendous explosion and the woman was sent flying into a wall, surprisingly unharmed, but dazed.

The creature then pointed to a man and said, "You! Is that your face, or did your neck throw up? HAW-HAW!" The man was sent flying as well and crashed into a dumpster. "You are so ugly, you make onion cry," the creature growled to another woman, sending her flying into a bus station. "And you," he said to the remaining tourist. "Your mama's so stupid, she gets hit by a parked car! HAW-HAW!" An explosion caused the man to fly into the sky and into the Seine. The creature then noticed Hellen and stomped his way over to her. "You are so ugly, you are banned from looking in mirrors! HAW-HAW!" There was an explosion, but Hellen stood her ground, much to the creature's confusion. Then he made a dismissive scoff and bounded away.

Hellen dusted herself off and adjusted her hood. "I think I'm quite beautiful. On my good side anyway." Then she heard footsteps and she looked across the street to see Big-Head chasing after the creature. "Mmm. There you are."

Big-Head caught up with Ladybug and Chat Noir, who were currently battling the Incredible Jerk. "So, what's the scoop on this guy," he asked Chat Noir.

"Well, you know the phrase words hurt? He takes it quite literally! Whoa!" Chat Noir ducked just in time to avoid getting hit by a tossed car.

"So his insults physically hurt you," Big-Head asked. An idea formed in his head. "Interesting."

The Incredible Jerk grabbed Ladybug's yo-yo and held her up. "Me love what you do with your hair. How do you get it to come out of your nostril like that? HAW-HAW!" Ladybug let out a scream as she was launched into the air. Chat Noir launched into the sky with his staff and caught her.

Big-Head approached the Incredible Jerk and shouted, "OI!" The Incredible Jerk turned to face him but before he could make an exploding insult, Big-Head shouted, "You are so ugly, that every day is Halloween!" The Incredible Jerk made a gasp and let out a growl of anger as he grew bigger. Big-Head gulped. "Oops," was all he could think to say before the giant squashed him like a bug. "Ouch."

"So insulting him back makes him stronger," said Chat Noir.

"Well, you never solve insults with insults," said Ladybug. "You need a gentle approach. LUCKY CHARM!" She twirled her yo-yo in the air, which created... "A rubber band?" She looked around and her vision highlighted a lamp post, a bench, and Chat Noir's staff. "I think I know what to do, but we still need to find the akuma!"

"Right here," said a female voice. Suddenly, the Incredible Jerk's body shrunk until all one could see was his skeleton. Then, he collapsed, revealing that Hellen had been the one who emaciated him with her knife Hunger. Then she broke the Incredible Jerk's belt buckle, causing the akuma to fly out. Then she took out her bowl Famine and blew ice onto the butterfly, causing it to freeze and shatter. Immediately, the Incredible Jerk changed into a young boy, but his body remained emaciated and he was groaning. Hellen said, "Do your thing, Ladybird Beetle."

"MIRACULOUS LADYBUG!" Ladybug threw the rubber band in the air and it exploded into a wave of red and black spots that repaired all the damage, except for the emaciated boy.

Big-Head slowly got up and said, "I'm okay. Okay." Then he turned and saw Hellen. "Who are you?"

Hellen smiled. "I am Hel. And that is my father's Mask you're wearing."

Big-Head scratched his head. "Hel? That sounds familiar." It is, you idiot! Remember, our talk with Alya and Marinette? "Oh, right. Well, it's been fun, but I gotta go." He didn't even take two steps before the ground and his feet froze. "Hey!" He took out a flamethrower and melted the ice and tried to flee, but Hellen stood in his way. "Whoa! Look lady, I've got places to go, people to beat up..." Hellen lowered her hood, revealing her half-decomposed face. Big-Head grimaced. "Now that's a face only a mother can love."

"Enough games, boy! Return my father's mask to me!"

"CATACLYSM!" Chat Noir destroyed the floor beneath Hellen's feet, sending her falling into the sewer. "Big-Head, get out of here now!"

"You know, for once, I agree," said Big-Head as he ran for his life.

Ladybug and Chat Noir heard their Miraculous begin to beep. "I'll take the boy to the hospital," said Ladybug. "You hurry and find a place to hide!"

"On it, m'lady."

Both Miraculous heroes disappeared before Hellen burst out of the ground. "This isn't over," she growled. "I will have my father's mask! None of you can stop me!"

Back at home, Rudi tore off the Mask and threw it under the bed. "Great," he said as he paced back and forth. "It's bad enough that we've got Ladybug, Chat Noir and that Lieutenant breathing down our necks. Now we've got a freaking snow goddess after us too!"

What's this "us" stuff? She's after me! Frankly, I'd rather go with her than stay with you, shrimp.

"That's not happening! If she takes you, everyone will know I'm Big-Head and my butt lands in jail!" Rudi sat down on the bed and buried his face in his hands. "What am I going to do now? Hel's going to find me, but if I tell anyone that a mad goddess is after me, they'll get suspicious and find out I'm Big-Head! What if I run away? Yeah. That way, no one can figure out I'm Big-Head and neither Hel nor Hawk Moth will find me!" Then he thought, "But what about Mom and Dad? They'll get worried and get akumatized. I mean, it already happened to Mom when I faked my own kidnapping! I'm between a rock and a hard place! I...I need to tell someone."

No! Then you'll go to jail for sure!

"I don't have a choice! I need to find someone to hide you! Someone who can keep a secret!" Then he had an idea.

Alya answered the doorbell and was greeted with someone wearing a paper bag over his head. "Who are you?" She got her answer when she saw the Mask of Loki in his hands. "You're-"

"Shh! Listen, I need to lie low for a while, and I need you to keep this." He handed her the Mask. "Can I trust you not to tell anyone about it? I'll need it back eventually though."

Alya said, "Why would you trust me? What's to stop me from telling Ladybug?"

Big-Head chuckled. "You know that new woman in town? Turns out she's the goddess of the underworld, Hel. And if she finds out you have the Mask...well, you saw what she did to Juleka." Alya gasped. "Yeah. So, yeah, I'll send you a letter if I need it back, byyyeeee!"

"Wait!" But it was too late, he already ran off. Alya looked at the Mask, made sure no one was looking and stepped back in her house.
