Mono is in the dim hallway with the carved door again.

Moving closer to the door, Mono touches the carving softly.

"What is it mean?"- Mono scrolls down each figure on the left -"Who are they? I have never seen them."

Mono then looks at the last one thoughtfully.

"Is this Six? Or someone else?"- Mono wonders as the figure is far too similar to Six.

"Didn't expect you to be so interested in them!"

Mono jumps.

"What?! Monaural?! What are you doing here?"

"You know that I'm your head, right?"

"Or maybe..."- Monaural says with a teasing voice -"Your ROmAnCe with Six's made you forgetful?"

Mono blushes.

"How can he know that?"

"Of course, I would. I'm in your HEAD!"- Monaural says as he pinches Mono's forehead.

"Ow! That's hurt!"- Mono says while holding his forehead.

"Really? Hahaha. I didn't expect being able to hurt you here."

"So, what do you want this time?"- Mono says since he has no other choice.

"Oh, Yes! Follow me!"

...

Mono and Monaural get in the casual room they used to be.

"Wait! What's this picture?"- Mono asks as he sees a picture of him and Six standing in the heavy rain, with him holding the umbrella for Six to refuge from the rain.

"Oh, that?"- Monaural says as he gets something out of a box -"I took it."

"What do you mean?! And HOW?"

"Oh! I didn't tell you that I can also travel OUTSIDE your mind. So I took it. Or should I say 'I remembered it'?"- Monaural says as he makes two cups of milk on the table -"Then, I recreate it here."

"What?! How could you get outside here? I thought that you are just a spirit..."- Mono says as he realizes something -"Refuging in my mind..."

"Yeah! That point!"- Monaural says with pride.

"Then how much did you see?"

"All of it!"- Monaural smirks -"I gotta say, you two are really bonding on each other."

Mono's face turns a bit red as he thinks -"OMG! He saw it all!"

Monaural smirks as he sits down on a chair -"Hahaha. It's fun to see you and Six hugs together. It's so ROmAntIc! Like an anime."

"Hey, Monaural! Can you stop stalking me, or Six?"- Mono demands Monaural, who he presumes being able to read his mind -"And stop reading my mind! It's not so fair for you being able to while I can't."

"Don't worry! I used it on purpose. Fun is just an extra."- Monaural says as he stands up, walks to the edge of the room.

Then, an iron and modern-looking door appears out of nowhere.

"Come here! This is what I want to show you."- Monaural says.

"Where? Now, you've made ANOTHER room in my head already?!"

"No, it isn't. Just come! It'll be quite an experience!"

Mono's still reluctant to come.

However, since he has nothing else to do but talking with his fellow friend, he comes.

.

On the other side, contrasting to all his presumes, It's not a room.

"What the?"- Mono is both confused and amazed.

He and Monaural are floating over a busy city that is beautifully lighted in the dark sky.

And, Monaural now wears a blue and shattered scarf around his neck and an eye badge on his right eye.

"Where are we?"

"To my knowledge, it's called Deika City."- Monaural says with a thoughtful tone -"And at this place, there will be a war."

"What do you mean?"

"Do you feel him?"- Monaural asks coldly.

"Wh..."- Mono says as he can feel a chill down his spine. Looking at the source, Mono sees a glitching tall figure in the wood near the city.

"What?! Is that really him, Thin Man?"

"Yes."

Mono looks at the Thin Man once again. This time, the Thin Man dead-stares at him, making him chilled.

"Don't worry."- Monaural says as he moves closer to Mono -"When I was traveling and looked at him, he sensed my existence."

"HOWEVER, that is not my concern."- Monaural says, which makes Mono surprised.

"There's another entity that has made moves in this world, wanting to infest and corrupt this world."

"What are you talking about, Monaural? You're scaring me."

"Do I?"- Monaural creepily speaks as he moves even closer to Mono, who's backing cautiously -"The entity...I can't defeat him without your power."

"Hey, Monaural! Are you fine?"- Mono keeps backing as he prepares to use his power if he needs to.

"So, May I borrow it?"

Mono keeps backing even more.

"Well. I guess I have to TAKE it."- And Monaural suddenly makes a cutlass and rushes to Mono with a death glare.

"SLASH!"

Mono dodges the attack in a clutch as slides in midair as if there's a foundation.

"Hey, Monaural! What's wrong with you? You were normal moments ago."- Mono says as he quickly stands up, waiting for another attack.

"Just say, I'm IN RAGE!"

Suddenly, Monaural's left eye starts emitting blue particles as he rushes to Mono furiously.

Mono dodges it in clutches again.

However, knowing that no sign Monaural is turning back, Mono decides to use his quirk.

Glitching particles appear around his hands, and so does his left eye. Mono suddenly feels Monaural, who's rushing to him, slower. Strangely, he suddenly feels excited to put Monaural down.

Then, the particles start forming a dark spike around his hand.

Ready to strike, Mono also rushes to Monaural.

The two rushes at each other at insane speed as their weapons crash.

OMG! Reviews! FINALLY!

I recently feel a bit worried that My CROSSOVER reached its peak in early May in views is because of the recent season release of MHA.

And Oh My. Seeing a review is like seeing a light at the end of the dark tunnel.

With no furthermore, Let's jump right into:

I.W.T.L.K

Mono 606 litezt: There will be other enemies that our protagonists will have to face besides those already mentioned.

TLK9999: Yes, indeed. Thin Man and the Lady aren't the only ones. Also, Some events in MHA may change.

.

Ham: I was thinking of the eye somehow taking control of mono and pretends to be mono maybe

ALSO, how do come up with these ideas?

TLK9999: The Eye will be in a different form. Neither the Tower nor Thin Man. (Sorry, that's all I can spoil). About the question, I am a very big fan of ANIME and MANGA so I read a lot of them, and most of them will stay in my brain for a long time. Some details may be borrowed from various animes. For example, the pre-version of chapter 13 is based on Episode 9 of the ANIME "SERVAMP", which I will keep for another chapter.

.

Ham: Demon Slayer

TLK9999: So you want another CROSSOVER. Interesting! I can do it but it's the sequel to this CROSSOVER so it may be a spoil. HOWEVER, If you viewers or readers want it so bad, Just review. 10 Votes and I will do it along with this.

This chapter is quite complicated to understand, I have to admit. But I want to spoil the plot a bit.

Also, Monaural is a plot character so everything he says should be considered when discussing the story.

Last words: If I reach 55 followers, I will post the power comparison between the main characters such as Six, Mono Monaural, and others.

Ask me any questions and I will post your comments at the end of each chapter until a new one comes.

Final words:

Thanks for reading my CROSSOVER.
