Megami and Kaga had a lot of potential than just being Kaga stalking Megami and pretty much being her stalker/creep that Yandere Dev made himself.
Instead of that, why didn't Yandere Dev make them childhood friends? Kaga's parents work in Saikou Corp. I'm sure Kaga would have met Megami during his youth whenever Megami had to leave the Corporation for her training, so why didn't he chose that path for them and have Kaga be the first male that Megami trusted? Kaga fits the criteria that the Saikou family is looking for (sure, he's at the bottom of the list, but he's there)
Kaga is quite intelligent and very talented at a very young age. Maybe if Saisho was able to see that, maybe he would have wanted Kaga close to Megami.
"If this boy is close to Megami and Megami trusts this boy, he can be a useful tool for Saikou Corp in the future."
Ichirou doesn't go against his father's decision. He never really argues with him either, so Ichirou has to follow his father's orders on keeping Kaga close to Megami. They will have to keep a close eye on him. If he ever did find out the dark secrets of Saikou Corp, Kaga would be killed by the orders of Saisho. (Just like Saisho did with Fungirl, but actually killed him rather than using a machine)
Saisho would keep a close eye on the two children whenever they were close to each other or hanging out.
Megami and Kaga begin to talk almost every day, which Saisho allowed. As time went on, the two became very close friends. Kaga was there for Megami whenever she needed him, and Megami was there for Kaga whenever he needed her.
The two continued to stick by each other's side throughout their years. Even after Saisho died, Megami made sure that Kaga stayed by her side if Ichirou had ever tried to separate and break their friendship, or if Kencho ever tried to set a trap to break their friendship.
Kaga would be a threat to Ayano if she killed him before and during Megami's week. Even if Kaga is her suitor, Kaga is someone important to Megami. If Megami loses him, who knows what she will do to put Ayano behind bars for his death.
So, let me give you guys some headcanons for this universe :>
They first met when they were 5.
Megami was quite distant at first because of how strict her family was until Saisho, himself, allowed her to see him and hang out with him.
Kaga was there for her during the tragic event of her murdering her hamster. (Megami's mother sneaked him inside) That day, Kaga promised her that they'll buy a hamster and take care of it together when they got older.
On her 13th birthday, Kaga made her a bracelet with his own hands to represent their friendship. He made one for himself, too. (And Aoi once she came into the picture) Megami hides her bracelet under her sleeves of her student council uniform.
Aoi and Kaga didn't get along well at first, but they slowly got close to each other and became friends. (Kaga is still scared of her)
Megami was slightly shorter than Kaga when they were children, but during the years and puberty, Megami grew taller.
Kaga would show Megami his new gadgets, invention ideas, etc. Megami would sometimes help him with building those inventions/gadgets (with a lot of protection, of course). That's how her love for science became.
Megami has a small robot that Kaga made himself and gave it to her to keep her company when they first met. She still has it in her room.
Megami forced Kaga to take self-defense classes. (It didn't end very well)
Kaga is basically Megami's cheerleader. He will cheer for her as much as possible to show that he is by her side and she can count on him.
Whenever Kaga gets hurt by an experiment, Megami will immediately take him to the best hospital in Japan and would be there for him unless she had training to do.
Kaga's parents feel uneasy having Megami close to their son. They know how strict the Saikou family is. They don't want their son harmed in any way. With time, they began to trust Megami. (Only her)
Once they enter Akademi, they are known as powerful friendship. The daughter of the richest and most powerful man in Japan and a mad scientist who is very talented and made the impossible possible. together? Power duo!
Megami has witnessed many competitions that Kaga has been in and won first place for. She tries to be there with her bodyguards and would take Kaga out to celebrate for his accomplishments with the permission of his parents, of course.
Whenever Kaga did his crazy smile or laugh when he got a new idea in his mind, Megami would smack him (gently) to make him quit, or shaking her head and say, "No."
Megami only lets Kaga show her affection (holding her hand, pecking her cheek, hugging her, etc). It makes him happy, and the way he shows love.
Kaga's parents sometimes tease Kaga about, one day, ending up liking Megami as more than a childhood friend. Kaga rejects this every time (but they were right in the end)
Kaga ended up catching feelings for Megami when they entered Akademi. At first, Kaga was confused at first on how his body was reacting to having Megami close to him or showing her affection, which is something he always did. Kaga never fell in love with anyone or saw anyone in a romantic way, so it was all new to him. With time, Kaga finally admitted that he caught feelings for his childhood friend. (His parents had a nice " I told you so." victory 😌)
Megami caught on to this. She's not blind. It's quite obvious from Kaga's body language.
Kaga never had the courage to confess because of many guys trying to win Megami's hand in marriage until the last year of Akademi, that's when he confessed his feelings to her under the cherry tree.
Megami did develop feelings for Kaga, but it took her more time to realize those buried feelings.
Kaga admires Megami a lot for her achievements, bravery, determination, and her hard work.
Megami would carry Kaga if he was ever too fatigued to move (after not resting for a certain number of days). Kaga found it annoying at first but got used to it.
Whenever Megami has free time (it's rare), Kaga would use this opportunity to go to the town with Megami to spend time together as much as they can.
Kaga would protect Megami from any guy who would flirt with her or look at her inappropriately. Megami would tell him to let her handle it and to calm down.
Megami is brutally honest with Kaga even if it hurts his feelings. She will say what she thinks and feels. (This is a headcanon I have as them as a couple )
If Kaga is killed, Megami will make sure to put Ayano behind bars. She knows she did it. After that, she will mourn for Kaga's death.
If Megami is killed, Kaga will find the person who caused her death and mourn for Megami's death.
This is probably something that would happen in another timeline not in the canon one, but it's a nice idea and interesting friendship :D
