Hi there, this is going to be a different one. I wanted to do something with To Love Ru, mostly because is the first Harem series to be serialized in Shonen Jump. I have read and I like, Rizo is a much more likable character than Issei, he is the style of Tatsuma from Rosario Plus Vampire. After a few volumes I wanted to do a crossover, but I need it to find a good series.

I wanna do a my hero crossover, but I saw there was enough of those, so I went with Black Clover. Asta has a harem, but now it will be a really big one. Let's have fun.

On a magical world.

The world was in chaos at first, a huge demon attacked the capital of the clover kingdom, almost killing a ton of people, but he was stopped by the first Wizard King, a powerful being who was able to kill that monster. After that the title of Wizard King was passed down to the most powerful and most skilled wizard of the Clover Kingdom, but it's a very tight race and very disputed.

At the village of Hage.

A boy named Asta was all excited, because today was the day of Grimoire selection. When a person of age go to get their grimoire, which would be their companion for the rest of their time. However Asta didn't had any magic, while his brother/rival Yuno was being seen as a prodigy.

''Are you really going there Asta?" Asked Siter Lily.

''Yes! I am going to get my grimoire and show you all that I can be the Wizard King!'' Said Asta.

''Make sure that Asta don't get lost Yuno.'' Said Father Orsi.

''Yes father.'' Said Yuno.

''Wait for me!'' Said a femine voice.

''Oh Haruna, come on we are leaving.'' Said Asta to one of his foster siblings.

The girl name was Haruna and she has been in the orphanage since Asta and Yuno, she had a good amount of magic, not Yuno level but a good amount for someone of her age. She was smart and king, but also believed in Asta dream.

''You three should be returning before noon. Make sure to wait patiently for your grimoire.'' Said Sister Lily.

''Yes sister Lily.'' Said Haruna.

''We promise that we wll accept what will be for us.'' Said Yuno.

''Good and Asta please don't be sad that you won't get a Grimoire.'' Said Orsi.

''You will see old man, I am going to get a really cool one.'' Said Asta.

''Please Asta, you screamed enough today.'' Said Haruna.

''Yes, we can't keep up with this shouting.'' Said Yuno.

''Oh come on!' Said Asta annoyed.

Yuno rolled his eyes while Haruna had a little laugh.

''Let's go.'' Said Yuno.

''Right!'' Said the other two.

At the Grimoire selection.

The teens were getting their grimoire, most of them were three leaf grimoires, which was the most common grimoire to get.

''Hey look at that girl´s grimoire.'' Said a person pointing at Haruna.

Haruna had got a three-leaf grimoire with a purple cover, she saw that had a lot about her magic which was gravity magic.

''I like this color.'' Said her.

She saw her grimoire and looked at that with a smile.

''Where´s Asta and Yuno?" Thoguht her.

She then saw Yuno with a great grimoire, it was sparkling, and a lot of people were looking in amazement.

''Uh?" Asked Haruna.

''Woah! A four-leaf grimoire!''

''Wow, he is going to be a super strong mage!''

However there was one person who didn't got a grimoire, it was Asta and he was shouting for the book to come to him.

''Come on! Come to me!'' Said him.

The other teens either laugh at him or felt bad for him, he didn't got a grimoire and didn't made any favor to himself, he wasn't getting anything.

''Asta.'' Said Haruna all sad.

''Looks like he is not going to anywhere. I guess I will be the wizard king.'' Said Yuno.

Haruna looked at Yuno with a glare, and even hit him in the ribs, making him grunt in pain.

''How could you say that?!'' Said her that.

''You don't understand, we are rivals, and we are always competing.'' Said Yuno all calm.

''you boys and your rivalry!'' Said Haruna all annoyed.

The two kept seeing their childhood friend as he didn't give up.

''Come on!'' Said Asta keeping shouting.

''Asta.'' Said Haruna all sad.

''He won't stop.'' Said Yuno.

The grimoire selection had to end, and the trio had to go home, Asta didn't wanted to look sad at all, he wanted to keep going on and how said he would keep working on getting his grimoire.

Later

A criminal named Revchi Salik had come to the Hage church, he wanted to steal Yuno four leaf grimoire. The criminal had chain magic and made sure that all the kids were restrained, making sure they didn't make a move, however someone appeared to save them.

''Stop!'' Said Asta.

''Asta!'' Scream the church people.

''I will save you all! AAAAAAAAAAH!' Scream Asta rushing to beat Revchi.

Revchi then started to beat Asta savagely, pretty much leaving him to near death state. The whole church was in horror at that as the criminal kept lauhgint.

''You are nothing but a worthless little worm, I heard you don't have any magic. How can you be something in this world if you don't have any power! You might as well be killed and left to rot!'' Said Revchi.

''Shut up!'' Said Haruna and Yuno.

The criminal looked at the two teens, who both looked at him with hatred.

''Asta might not have magic, but he works harder than anyone I have ever seen! He is dedicated, kind and is worth of great accomplished!'' Said Haruna.

''She is right! Asta is the most hardworking person i´ve seen. He never gives up and will never let anyone boss him around! This is why he is my rival!'' Said Yuno.

The speech from the two made Asta get up and have faith again, he felt power this time and he would use it.

''They are believing in me, I need to get back up and save them!'' Thought Asta.

Soon a dark presence was around the field. Soon something appeared out of the ground of the church, a dark grimoire and it looked all dirty and old.

''A grimoire?" Thought Asta.

Asta didn't know why but he felt attached to that grimoire.

It said that a three-leaf grimoire brings the user a good amount of power, the four leaf grimoire brings the user a great amount of luck, while the five leaf grimoires resides a devil.

''What is this?' Thought Revchi in confusion.

Then Asta charged at the criminal, he bashed the chains with his massive sword that spread it out of the grimoire and once that was took care of he beat the criminal.

Bam

Once the criminal was defeated, Asta felt a great sensation.

''I did it! I won with my grimoire.'' Thoguht Asta.

''Asta!'' Said the church group going to him.

They all hugged him and were all happy that was he was ok, and he saved them.

''I knew you could have a grimoire, I always had faith for you.'' Said Haruna.

''Thanks, I knew that I would get one.'' Said Asta.

''I always believed in you Asta.'' Said Father Orsi.

''You never said that old man.'' Said Nash.

''Shut up!'' Said the father.

Asta then saw Yuno, who had a puzzled look in his face.

''Yuno?" Asked Asta.

''Asta, you show much more power than I ever imagined. I knew you were stronger, but you show to get even stronger. I won't give up, I will keep working hard to become the wizard King.'' Said Yuno.

Asta just smile at that, their rivalry was still going on.

''Right! Lets see who become the wizard King first!'' Said Asta.

The two-fist bump, making sure that they would work their hardest.

''You boys never change.'' Said Haruna.

The group just smile at that, the boys were back at their regular way.

In Space

A being called Lala was running away from her trouble, she was looking for a place to hide.

''I need to hide and it's a place with power!'' Thoguht her.

She looked with her ship for someone with power, she then sensed a lot of energy coming from a certain planet.

''This planet looks good.'' Thoguht her.

So yes, Lala is going and Haruno lived with Asta and Yuno. I thought that was going to work a lot, I felt that would fit in the story. Let's see how they would work together. Lala will appear once asta join the Black Bulls.

Let's go and have some fun.
