Here is my Loud House/Your lie in April crossover, it is set 6 months after the show of Your lie in April and 1 year after the Loud House and here we go:

Lisa Loud was working on a invention, a revival implant, it would give the person an ability to revive people from the dead.

She decided it was best tested by Leni, she was the sweet hearted one and the one that is easiest to manipulate.

So Lisa convinced Leni with the promise of fashion equipment in order for the test

"will this hurt" said Leni scared

"No" said Lisa creepily like when her secret projects on her siblings are revealed

Leni is injected with the implant without any pain, surprisingly and she given new fashion equipment as an award.

One day Lincoln won a trip to Japan to meet one of his favourite Cartoon creators, since he couldn't be trusted on his own, Leni was hired to look after Lincoln in Japan (As Lori was now at college with Bobby).

One night Leni wandered off outside the hotel where she ended up in a graveyard

She ended up looking at some of the graves, some dying too young.

Leni accidentally touched one of the graves and due to the implant something happened, an energy came off her hands and was causing the ground to shake as well as her hand which tore apart the tombstone and then a large bang.

Suddenly she heard a thing knocking about underneath.

"Let me out" said the voice in Japanese

Leni could understand Japanese, after all while she maybe be a bit dim, but she isn't a total airhead as she loved discovering different cultures and languages, she could speak English and Russian prior to learning Japanese and their culture.

Leni dug a bit and pulled open the casket to find a weak looking cream blonde girl who was seemingly buried with her violin and in her pyjamas.

"Who are you" said Leni Loud in Japanese

"My name is Kaori Miyazono and I was a musician who fell in love with this boy named Kōsei Arima, in fact I believe I was dead and now suddenly I'm alive now, who are you" said Kaori in Japanese

"My name is Leni Loud and I'm not sure what happened, something fired out of my hands and then you banged loudly on your box thingy and suddenly I see you" said Leni in Japanese

"Ah do you know a Kōsei Arima" said Kaori in Japanese

"Nope, I'm not Japanese, I'm American" said Leni in Japanese

"I'd guess not, I guess he mourning me badly, (her motions change), oh gosh has he got the letter that told him that I loved him" said Kaori in Japanese

"Oh gosh, have you got parents to turn to" said Leni in Japanese, feeling sorry for her.

"They must be struck with grief, I must go and see them" said Kaori in Japanese

Kaori tries to run but falls over, so Leni picks her up and carries her to the location of Kaoris parents bakery.

However when they got there, Kaori saw something that upsetted her.

Her parents old bakery was boarded up and closed and she read the note on the door 'Hello I'm afraid that we've shut down the bakery, our grief for our daughter has caused us to move to the USA to start a new chapter in our lives, thanks for the memories'

"There gone, they moved away" said Kaori in Japanese

"I'm sorry" said Leni in Japanese

Kaori couldn't believe her eyes, her parents were no longer in her home town, they had moved away and there was nowhere for her to go, but she had an another idea.

"Why not she check up on Kōsei, see if I can cheer him up" said Kaori in Japanese

"Ok, be careful though, I'm not very strong" said Leni in Japanese as she picked up Kaori again

Kaori whacked Leni a few times in anger before she agreed to go to Kōseis,

When Kaori and Leni got there though, she could see a new family move in where Kōsei used to be

Also it appears that Tsubaki has also moved out as well as a another family with different kids appeared at Tsubakis old home.

"Where do I go now" said Kaori in Japanese as she cried on Lenis shoulders

"I can look after you, until you find your friends and family" said Leni in Japanese

"Really, I barely Evan know you, although this is a bit sudden, but I'm hungry after being dead for a while" said Kaori in Japanese

"Yeah my treat, just let me wake up my brother and we will go get some fast food" said Leni in Japanese

Leni walked Kaori back to her hotel where she opened the door and flickered the lights

"Linky, do you fancy some fast food" said Leni who left Kaori outside her room

"Are you sure your not joking" said Lincoln jumping out of bed surprised.

Leni had been making sure Linky had a healthy food balance in Japan which gives off the impression of Leni trying to be an overprotective parent despite being his sister, not mother.

"Not a joke, found this poor disabled girl outside named Kaori and want to help her, so I'm taking you both as Mom said that I'm to watch you" said Leni

Had Kaori understood that sentence especially being called disabled, she would of shoved both of Lenis sandals into Lenis mouth in anger

As the trio walked out of the hotel, they headed towards a burger joint and while getting burgers, Leni settled Lincoln and Kaori down

"You two be good, I'll get the yum yum and it will be time for food" said Leni being as overprotective as always.

Lincoln greeted Kaori in Japanese (after all, he understood Japanese quite well due to all of the manga and comics he read) "Hello Kaori, I'm Lincoln, pleasure it is to meet you"

"Hello Lincoln, pleasure it is to meet you" said Kaori in Japanese

"So where did you come from" said Lincoln in Japanese

"Well I'm come from here, but I believe that I died a while ago and after a vision with my crush Kōsei, a blue light flashed in my eyes and awakened me and then your sister opened up my casket and here we are" said Kaori in Japanese

Lincoln knew exactly where Leni had got those powers from, after all Lisa tried to offer that experiment on him in offer for some Ace Savvy memorabilia, but he refused, it seems Leni had willingly volunteered in Lincoln's eyes.

Also Lincoln knew that once it revived someone, the power could not be used for another 20 years, despite Lisa's disturbing experiment, it seems this one had come out with a good result, a nice looking girl has now a 2nd chance of life

"So this Kōsei, is he still alive" said Lincoln in Japanese

"Yeah he is still alive hopefully , just don't know where he is, he moved out of his old home" said Kaori in Japanese

"Lets hope so, so how did you die" said Lincoln in Japanese

"Fredrick's Ataxia" said Kaori in Japanese

"What's that" said Lincoln in Japanese

"It's like Lou Gehrings Disease, only younger people get it and Cardiac arrest is also one of the symptoms, I also died on the operating table" said Kaori in Japanese

"do you feel you have it now" said Lincoln in Japanese

"No apart from I can't feel my legs, which is probably a scar from the disease" said Kaori in Japanese

"Yeah, Leni got those revival powers by my sister called Lisa Loud..." said Lincoln in Japanese before being interrupted

"You mean the child prodigy" said Kaori in Japanese

"Yes, anyway she injected Leni with revival chip which mean she can resurrect 1 person every 20 years, their old diseases cured, although scars of the old disease remain" said Lincoln in Japanese

After Lincoln said that, Leni arrived with the burgers, "eat up everyone" in Japanese as both can understand it
