We see the boys hanging out in the basement with the both wearing robes.

Windle-chan: Are you sure this will work?
Forest: Of course.

Jack: Yeah. Father and I did this all the time.

Dunkerque: This is a bit worrying Kapitaine.

Dunkirque said as she still looks at Jack Warily at Jack who smiled at her. She felt the blade almost pierce if it wasn't for Forest then she would have been dead.

Windle-chan: What even are servants onkel?

Windle-chan asked causing the french girls and everyone to look at Forest, who is drawing a magic circle on the floor.

Forest: Well, Servants are spirits made into special familiars of the highest rank, that are bound to the Master. Typically Heroic Spirits under most systems, they can also sometimes be Divine Spirits, Phantoms, Wraiths, and living people depending on various circumstances. Pure Heroic Spirits, the "main body" in the Throne of Heroes, can only be summoned by the World, and summoning even one is considered to be a miraculous occurrence. Differing from the normal definition of familiars that can be likened to minor mascots unable to be stronger than their masters, Heroic Spirits are the most powerful of beings. You can summon a heroic spirit from the past present or future due to the throne of heroes existing outside of time and space.

All the people in the room who were unfamiliar with magecraft was shocked. To summon Beings of absolute power nonchalantly, there is indeed something wrong with their kapitaine or in windle-chan's case, His uncle somehow made his head hurt again.

Forest: Also Jack is a servant who is an amalgamation of the spirits of unborn children from 19th century London who then took the form of and abilities of  Jack the ripper.

That broke the everyone of them and suddenly they were shocked out from their shock when the circle shone brightly.

Forest: Ok Windle-chan recite this.

He gives his nephew a piece of paper who opens it and reads it. Forest then takes out a golden cup that radiates power and places it inthe middle.

Forest: some parts of them are blank for you to fill up on.

Windle-chan:

Silver and iron to the origin. Pride and the Glory of contracts to the cornerstone.

The ancestor is my great master Schweinorg.

The alighted wind becomes a wall. The gates in the four directions close, coming from the crown, the three-forked road that leads to the kingdom circulate.

Shut (fill).

Shut (fill).

Shut (fill).

Shut (fill).

Shut (fill).

Repeat every five times.

Simply, shatter once filled.

――――I announce.

Your self is under me, my fate(doom) is in your sword.

In accordance with the approach of the Holy Grail, if you abide by this feeling, this reason, then answer.

Here is my oath. I am the one who becomes all the good of the world of the dead, I am the one who lays out all the evil of the world of the dead.

You, seven heavens clad in three words of power, arrive from the ring of deterrence, O keeper of the balance ―――！

A bright ligh blinds everyone in the room and when the light dies down a blonde-haired girl is seen wearing a dark dress and carrying a stuffed teddy bear.

??: Hello! I’m Abigail--- Abigail Williams. I’m from the, Fo...reigner...class. Are you the Master? If it’s okay with you, please call me Abby. I believe we’ll quickly become friends

She smiled at Windle-chan and he smiled back at her. He has a new friend and when he looked at the others He saw a happy Forest, An excited Jack and worried French shipgirls.

Forbin: Abigail williams...

Le mars: If I remember correctly she's the one from the Salem Witch trials.

Dunkirque: Kapitaine please stay away from the witch.

Forest: Calm down everyone Abigail isn't!

Forest was cut off as Abigail started to tear up and was about to cry when tentacles sprouted up into the air and a keyhole appeared on her forehead.

Forest: Shit! calm down Abigail!!!

Windle-chan: What's goin on.

A memory of a young girl scared and alone appeared on his memory. Knowing what to do Windle-chan went to Abigail and hugged her calming her down. Abigail then started to cry at Windle-chan and Forest gave a disappointed look at the french girls.

Forest: Apologize...

He said quietly yet the look on his face scared the french girls although it did make them feel hot for some reason.
The french girls apologized and befriended Abigail and they spent the rest of the fay catching up.

Meanwhile

We see Zeppy crushing a plastic cup and looked angry as her riggings appeared l.

Zeppy: A rival appeared.

Graf Zeppelin saw her daughter having a determined look. She was glowing and smiling happily.

Graf Zeppelin: what seems to be the problem.

Zeppy: I felt a rival's appearance.

Graf Zeppelin: Blame your father, Forest.

Zeppy slammed the desk in shock as she stared at her mother.

Zeppy: When did that happen?

Graf Zeppelin smiled and toom out a photo causing her daughter to blush.

Graf Zeppelin: The same day I saw you being confessed at by Windle-chan you two were so cute!

Zeppy: F-forest a-as my f-father?!

Zeppy fainted at the shock as she heard stories of the commabder from her boyfriend

Graf Zeppelin: Kids. Although you should prepare yourself Forest.

Graf Zeppelin smirks and licks her lips.

Graf Zeppelin: I will enjoy next time.

In Sakura empire

We see Hiei gripping her katana tightly.

Hiei: I see, it seems like someone made their move at my husband.

Hiei-chan: Future husband.

Hiei: Very well then they shall prepare for only the best is suited for commander.

Hiei-chan merely sweat dropped at her mother.

Hiei-chan: Poor father, being caught in the middle of so many girls.
