so remember somewhere in ddlc wiki, that natsuki was poorly treated by her dad?

The Story i'd call is "The Rage"

because it feels like natsuki has hatred to her dad.
for how he treated her.

So far all i have in my mind was Monika Fight

Where Monika dosent claim to be mother but she is somewhat a figure of it.

that it reminds natsuki what her dad and mom argue was and how it affects Current Natsuki, because this is what it looks like to their vision.

Natsuki was about to follow her abusive dad's footsteps, and Monika was just like a guardian.

Monika of course dies by Natsuki's Mercy Kill

because she was about to erase the world, and make that 100th time, so natsuki wouldnt do get her revenge.

The Final Fight With Dad has Only 3 Phases.

Dad being Guilt Tripping and caring lesss man he is, throws fits that he worked harder for natsuki's needs, such as Eletricity, Food, Accessories, Decorations.

he paid rent, all of it for his family to be healthy, Natsuki was treated poorly because her dad never acknowledged her. he only did it ONCE, and never again.

After The Fallout with The Mother.

Natsuki wants to end her dad's misery.
but for some reason she cant bring herself to do it.

she managed to take down monika, what would stop her?

in Phase 2, She was shot at by her dad, because natsuki had illegal firearm, and with it, her dad could be in clear due of crooked officers.

Natsuki was about to die, and join her mom, but then Sayori stepped in.

She helped Natsuki, came to help her a bit, but even then, she died protecting Natsuki.

with that last Straw, Natsuki and her dad have the final fight, and it was never about family or wealth carrying

Natsuki had her own fate to chase.
