I Swear at this point I'm making self inserts only to name my Tumblr side blogs
Gotta say this, It all started like a "let's see how much I can predict of the future Deltarune secret bosses", but I must admit It actually turned out as some good work!
Let's see how much I can explain about them, without getting lost!
Ok, so First of all, being a self insert, their pronouns are He/him - She/Her. If you're lazy like me, you can use They/Them, but the other two options are the best to go, plus, are very much more in character!
Thus, making her Bigender. Again, She's a self insert.
Same reason makes her Bisexual as well but It's not very important for this character.
Now that you know how to fall in love with him let me explain this character, as per an In-Game One!
I imagined her Chapter being dedicated to Fine Arts, with the setting and characters developing similarly to "Ib", but with every form of Art.
With him being a librarian, always at his desk, writing silently.
He'll claim, rightfully, to be the author of every book you'll find in there.
The doors of his library would always be open for Kris and the party to enter and look around.
You can in fact read the books: 2 per every shelf.
Every book will be someone's story, told in different ways, even manuals or gossip collections can tell you a lot.
You'll get to move books around and change their location.
You'll end up noticing that 4 books all around are missing.
To engage in battle, You'll have to bring her 3 of them. One by one, so She'll have the time to fill in the documents regarding the books, and make each one tea.
With the tea ready, the battle will begin.
Any route will have the same start: Kris' soul turnig green and being unable to move.
In a Pacifist Route, ExEcutionHeir will ask you to talk about your adventure in the dark worlds.
This meaning that your ACTion choices will make you able to tell your tale, the way you desire.
At his turn instead, he'll shower your soul with his tea's drops: some being normal attacks, the other being green healing drops. You are forced to take them all, as you can't cover yourself, differently from Undyne's battle.
The attack drops are to encorauge the party to eat items, while drinking his tea.
In fact there will always be an attack drop more than healing ones.
Each attack drop will take away 2 HP.
Each green drop will heal 2 HP.
If you don't heal your party, and your HP lowers to 42, She'll swap the healing/attack drops proportion.
The battle will feel as cute and friendly, until you'll tell him that you spared the Spade King's life (and eventually any other evil final boss before him).
There you'll be freed, Kris' soul turnig back red.
Enraged, ExEcutionHeir will actually fight you, believing you should've execute the Evil ruler(s?)
Believing and telling you that leaving those people to fool around will out everyone at risk.
She'll try to submerge you in blank pages and cut your head off eventually, only to write your story with your blood.
Talking her out of her rage She'll realize She has become the very thing She hated most.
Not wanting to fight anymore She'll turn in a book cover, asking you to bring her around, "in return She'll cover your shoulder".
A weird route will make the ExEcutionHeir fight back istantly.
He'll believe his very mission is to end you, telling you that's always been his fate.
From that She'll tell you her story backwards.
Telling you She's written a lot of books, many against her will.
The one's missing for exemple was ordered to her, but still regrets her actions to these days.
He'll tell you that many are the people in loss coming to his library to honour their loved one's memory, and remember all the time gone, by reading their story again and again.
He'll tell you that many would've asked to be killed this, way only to leave their memory to others.
But He would refuse, as not everyone deserves an execution.
Often not even those who receive the treatment.
Having to kill so many innocents, brought her to develop a second consciousness (the writings in red) that not only confuses her thoughts, but actually keeps and protects her from remembering further.
She'll tell you that She never really wanted to hurt anybody, but was forced to handle this job, being her family's heir.
Plus It's a burden not many would've survived handling.
Defeated by his own feelings he'll turn into a nib as your weapon.
