Ruka and Maria were lovers in the past life. Stage opens with Maria's dying moment from 250 years ago as Ruka and Maria shares a song (according to the pamphlet, the song is called infinity)
Then they part as time moves to present days.
Girls (minus Maria) gather to chat, songs performed was Tomo Yo and Ame no Doubutsuen.
You won't believe how LAME they SQUEEZED Ame no Doubutsuen in. Won't touch on that.
Maria joins the girls but leave soon after. On her way home, two gangsters tries to hit on her. Maria can't be bothered to entertain them and they got nasty, taking knives out.
RUKA APPEARS.
But gangsters apparently cannot see Ruka and Ruka works magic and almost kills them.
Maria walks up to her.
Ruka: We finally met, I've been waiting for you for so long.
Maria: HI I AM MARIA, 17 YEARS OLD, MY FAVORITE FOOD IS STRAWBE...
Ruka: *KISSES MARIA*
Maria: WTF ARE U DOING D:
Ruka: We are fated to be in love.
Maria: WTF ARE YOU TALKING ABOUT D: WE JUST MET D:
Ruka: My heart is beating wildly, arn't yours?
Maria: HUHH!? WHAT. WE JUST MET. WHY SHOULD I BE EXCITED.
Ruka then breaks into song and sings Blue Rose.
... I know. I cannot explain enough how awkward the transition is but all is forgiven cause Sayaka's Blue Rose rendition was mind blowing.
Next scene of girls (minus Sempai team aka Iwasa and Yonezawa) at beach, singing Fushidara na Natsu.
Story setting: Natsuki bringing the girls to the beach for a break or so it seems but she's trying to make them buy eight million boxes of Yakisoba so that she gets a pay rise
One of the guy hits on Nakatsuka and she breaks into a FnN solo lololitwassobad
Then girls go into hiding as police pops out and the male actors dominates the stage for awhile
-
School scenes starts again and Natsuki + girls gets screamed at for running off to the beach. Maria floats into the room, staring at the blue rose Ruka gave her while being dreamy. Then she floats out of the room again and into Ruka's house.
Maria confronts Ruka but Ruka kisses her again and tells her about their past.
Maria is slowly but surely getting attracted to Ruka again.
But being confused she runs out of the house.
Ruka: I shall give her eternal life for sure, this time.
Maids (Tanamin and Nakayan): Then let us teach you how to use a keitai

People of this age uses this to express words of love.
Then they break into Renai Kinshi Jorei.
Next scene shows 109, and yes duh, girls sings 109 with Maria leading.
She is confused and sad.
Ruka appears, and confesses for the 2893748923th time that night. But Maria finally opens up to Ruka.
Maria: We live in too different a world.
Ruka: But after tonight, things will change.
Maria: Just step on your heart's pedal.
Both sings Hizukehenkousen together.
Vampire hunter appears and fires a bullet.
Ruka: Why do human never accept things apart from themselves.
Hunter: Shuddup freak.
Ruka: And you are not one?
Hunter: I am different from your species who live on human's blood.
Ruka: And do you not kill animals to feed on.
Hunter: Oh shuddup. *attempts to kill again*
But fails as Ruka uses magic to throw them off stairs.
Maria snuggles up to Ruka and receives her first bite.
-end of act 1-
*note: and my recording for act 2 is HORRID so from here on, I am writing based on what I can remember.
Act 2 opens with Honehone waltz by the maids accompanied by a mini skit.
Then curtains to the stage opens as girls sings Mori e Ikou.
Settings in the forest as the girls search for Maria.
They meet the hunters along the way and the hunters convinces them to lure Maria out of the house for they cannot fight Ruka inside the house due to wards.
Girls agree and they barge into the house screaming at Maria to wake up and leave the place to return to school.
Ruka wants her to stay, asking if the love they share was enough for her to choose this path but Maria is scared shit and breaks down as the girls continue to scream and screech at her.
Seeing Maria break down kills Ruka's heart.
Thus, Ruka makes a decision.
Ruka: This is your life, and you should live freely. I did not wait 250 years to make you sad. Nor did I wait 250 years to see your tears. Go. Be free. But remember that I will love you eternally.
Maria thanks Ruka and promises to love Ruka for as long as she lives, and proceeds to leave the house with the girls.
Maids: Is it okay to just let her go? You've been waiting for her for 250 years.
Ruka: Love is not to be binded... I know that but why is my heart so crushed and why does it hurt so much.
Ruka Kimi wa Pegasus solo.
Maria wakes up in a bed, sings Nakinagara Hohoende and misses Ruka.
Ruka appears and sings Infinity ballad version.
Ruka hugs Maria on the bed but hunter sneaks on Ruka from the behind,
and kills Ruka.
Maria runs up to Ruka and begs Ruka to bite her.
Ruka obliges and does so as the curtain falls.
Maria's voice narrates in the darkness.
Maria: And that night Ruka, turned into ashes in my arms. But this time, it is my turn to wait, I will wait like you did, and till today, the small scars at my neck is our sign of eternal love.
Dance competition happens as the girls perform Saishuu bell ga naru.
Ending, Yakusoku yo with full cast.
They used the line "Kanarazu kimi ni aeru kara" (I will definitely meet you again) as one of the main theme of the storyline.
