Here we go:
Kaori was at the Royal Woods hospital, she knew that she'll leave hospital on the weekend, Doctor Nield was left to check on her quite often as part of the hospitals concussion awareness program
Kaori did have a slight headache (from the concussion) and was lying in bed to see people rushing around panicked, Doctor Nield followed them,
"I wonder what's going on" muttered Kaori
Soon a stretcher rolled through and Kaori then saw Rita and Lynn Sr
"Wait what are Rita and Lynn Sr doing here, what's going on" said Kaori as she wandered out of her bed, one hand to head because of the headache
She wondered where all of the comotion was going on to see Lynn Sr and Rita outside of two closed doors, that was the ICU.
She ran towards them which they turned to notice "Hey Kaori" which Kaori hugged them both and teared up and said "What's going on, what's happened"
Soon Doctor Sheppard came out
"Hello is the parents of Leni Loud" said Doctor Sheppard
"Yes, also this is her foster sister, Kaori Miyazono Loud" said Rita
"Ah Kaori, did you know that you can leave early, your headache is all that's left right " said Doctor Sheppard
"Yeah, everything has gone away" said Kaori
"That's good news, anyway I need to you three in my office" said Doctor Sheppard
They went to his office where they all sat down
"Well here it we goes, we did all that we could" said Doctor Sheppard
"Wait she's..." Said Rita crying
"Yep, she's gone, she passed away from a combination of a Stroke and a Cardiac Arrest, I'm sorry" said Doctor Sheppard
Kaori was crying very loudly which both Rita and Lynn Sr comforted her, then a surgeon came in
"We found this inside Leni" said Doctor Parry holding Lenis revival chip
"That's a revival chip made by Lisa Loud" said Doctor Sheppard
"It's the same one that revived me" said Kaori with tears in her eyes
"I think Leni would want you to have it then" said Doctor Parry
"Can we see her for one last time" said Rita
"If you must" said Doctor Parry
The 3 went in the ICU to see an expired Leni Loud, she looked lifeless, her face looked like she struggled before death, that image would forever haunt Kaori, Leni also looked pale.
They stared at her corpse for 30 minutes before saying their final goodbye and they left the building , taking Kaori with them
As them 3 walked out, Lynn Sr and Rita comforted Kaori, she was massively devastated
Then she told her foster parents
"I've got to tell you something" said Kaori
"What is it Kaori" said Lynn Sr
"I'm pregnant, this time with Kōuseis child" said Kaori
While it was shocking news, it appeared to cheer Rita and Lynn Sr a bit
"You know Leni once said you and Kōusei would have a great family together" said Rita
