Let's go back in time , when the whole group split .
The three girl were on the way to the Smith's tower . Arika was happy to be in Garderobe again but she know that she wasn't here to follow lesson with their classmate or even eat a lunch with Erstin and Nina . She was here to takes revenge for Erstin' death and to stop Nina and Nagi before they started to destroy the other cities .
' Nina , smile . If you are upset or depress , we're gonna te be arrest .'
' I would like but , I can't ..'
' Arika , please , smile .. I like when you're smiling .'
' Mashiro , I also liked when Erstin was doing it .'
' Arika , please , forget it . If you're thinking about it during a fight , you won't be focus on your opponent .'
' excuse me but who is Erstin?'
' Erstin was ..'
' No , Mashiro . Let me explain . Erstin was a friend of mine but it turn out that she was a Schwartz's spy . She died during the attack of Garderobe .. Nina killed Erstin's slave as she was trying to kill me . So Erstin died After her Slave .'
' Gomen , Arika . We won't talk about that anymore .'
' That's Ok . I must go over it . It's on the past , and the present is what we're gonna do right now , isn't it ?'
' Yeah .'
' You see , you're smiling again !'
' Yeah , Mashiro ..'
' Girls , stop it . We are arrived .'
' How are we gonna sneak into the tower ? there is too much Guards !'
' We have to fight . Arika , Materialize . It's not gonna be easy .'
Then , in a small street near the tower , Sarah and Arika materialized their Robes . then , they put their cloak back and the three girl started the attack ..
Sarah started by kill the two guards on the front door . Then another came , and tried to contact the QG but Arika killed him before he had the chance to do it . The front door's area was clean .
' Good job , Arika . let's move on .'
' Sarah , I was wandering .. what kind of weapon have you?'
' Oh . Great question Arika . You see this dagger ? This is my weapon .'
' Are you kidding ? Arika's one is so much bigger , yours wouldn't able to hurt someone or maybe a rabbit , but I doubt it ..'
' That's why this weapon is dangerous , Mashiro . Keep the image of my dagger in your head because it gonna be change .'
' What do you means , Sarah-san ?'
' Me , Sarah Gallagher , member of the Five Pillar , ask the Great Milky way , to give me her whole power , to let me defeat the opponent .'
Then , a dark aura comes around Sarah and the tiny dagger started to enlarge to become a great and long sword ornate with arcane's symbols .
' That's so greaaat …'
' Impressive ! How this dagger can become a master sword ?'
' That's the power of the Milky Way . The cosmos has always been my best ally .'
' Excuse me , Sarah . I've acted like a fool .'
' Don't be . Let's move on .'
Room After Room , the two Otome was progressing in the tower .. But a biggest danger was waiting for Arika .
Interlude 2 : Nagi's QG' Nao-chan is really impressive . If I knew , I would choose her instead of Nina ..'
' Your Highness , what are you ..'
' Calm down , Sergay .'
' Your Highness ! there is a second field attacked !'
' Interesting ..Show me who are the opponent this time !'
' Looks like there is Mashiro-hime , and two Otome with her ..'
' Great ! Nina ! Come here , please !'
' Yes , master . your order .'
' Look at this screenshot taken by the tower's camera . Don't you recognize someone ?'
' Arika !'
' What ? What Arika is doing here ?'
' Oh , that's so touching … Nina , even your father is worried about Arika's presence .'
' Father .. let me makes this case clear . I'm gonna go to the tower and talk with Arika to makes her stop this foolish act …'
' I refused .'
' Archduke .. why ?'
' Because Nina is my Otome before your daughter so it's you Sergay , who is gonna to get rid of Arika and the Otome who is with her . And bring me Mashiro when the job will be done .'
' Understood .'
' Father , wait ..'
' Don't Nina . I have to do it if it's an order from the archduke'
' But ..'
' I will come back , it's a promise .'
' Now , Sergay , let's go . Our opponent will be soon at Rena's grave ..'
Part 2 : Arika / Mashiro / Sarah , Second Part' We're finally here .'
' My mother is on this room ..'
' Arika , you have to hurry . Sorry but I promise you to make a great ceremony for your mother when Garderobe will be free but right now , we have to hurry .'
' Thanks Mashiro .'
Arika open the door and notice the great machine where her mother was keep in . Mashiro was about to follow her but Sarah stopped her .
' Don't Mashiro . She has to do it by herself .'
' But ..'
' Don't , really . Please'
' Right .'
The room was deeply in the darkness . Arika was moving slowly and their eyes were open . When she touch Rena's grave , her necklace started to Rumble and as she was about to stab the machine with her weapon , the light came and Sergay enter in the room .
' Arika , don't do it .'
' Sergay .. what are you doing here ?'
' I'm trying to stop you .'
' How can you pass this door ? Sarah would stop you ..'
' Mashiro let me in . She said to the other that it would be another thing you want to do by yourself .'
' Anyway , Leave . I have to destroy this machine to get back Mum's corpse and to send all the GEM in Shinso back .'
' You know what ? I known your mother in the past . And I felt in love with her . But I was younger than her and she was already taking care of you . But After a few hesitation , I succeed to talk with her and I stayed with her every singles times I can . I saw her taking care of you , feed you and playing with you …'
' Stop it ! Don't tell me these things right now ! I've also a duty to do .'
' No , You listen to me ! I felt in love with Rena and when I find out that you were Rena's daughter , I was already in love with you … Isn't pathetic ?'
' Don't call my Mum by her name ! And don't dare telling that you felt in love with me !'
' That's the true , Antsy ..'
' Stop it . Stop it , Sergay !'
' Please come with me , I'll ask Nagi a favor about your punishment and for Mashiro's too . It's a promise .'
' I won't . I want bring peace to Garderobe again ; and Nagi wants to bring chaos . Our goals are different . You choose the wrong side . Assume it !'
' Arika , Please … I'll do everything to you if you stop ..'
' Kiss me and I stop ..'
' Arika , if I kiss you , you wouldn't able to be an Otome again..'
' Sergay ..'
' Right , if you really want it , I'll do it .'
then the two lovers hug each other . Their lips were closer but before Sergay's lips could touch Arika's , the girl stab Sergay in the chest with her weapon . Blood come out and he felt dawn on the floor .
' Arika , Why …'
' It was the only solution . If you told Nina that you were support me , maybe she wouldn't going crazy like she is now and Erstin would be still alive . All these is because of you !'
' Arika , you're wrong . I never wish these things …'
' Sorry , Sergay . Your death will be the beginning of a new area as Erstin's death was the beginning of an chaotic one.'
' Maybe , you're right .. Please , when you'll fight against Nina , Tell her that she'll always be my daughter and that she'll never left my heart , as you too . I used to love your mother ,and I loved you too …'
' Sergay , I'll also love you forever !'
' Thanks , Arika…'
And Sergay died . There were tears on Arika's face . Too much pain , too much love… Arika break down and cried on Sergay's corpse . Sarah and Mashiro came in .
' Arika , I know that a painful decision but you'll have time to cry about Sergay's death later . We've to destroy this machine ..'
' Sarah , please , do it by yourself . I really can't …'
' Arika , I'm sorry ..'
Mashiro suddenly hug her Otome and touch by her master's tenderness , Arika cried on her shoulder .
' Sergay !'
' I'll be always by you , Arika . I promise you that I'll never betray you ever .'
' Arigato , Mashiro .'
Then Sarah took her sword and cut in two part the machine where Rena was keep . All the GEM stay during a minute in the air and they flew to Shinso's . Then , without reasons , Rena's shadow appear ..
' My dear daughter , you've become so beautiful ..'
' Mum ! Mum ! You're alive !'
' No Arika , I'm not , but I saw what you've done . Sacrifice her own Love to preserve the world's peace , It's such a great act .I'm so proud of you .'
' Mum …'
' You have to follow your way but remember I will be always with you , my love .'
Then the shadow disappear and Arika's necklace shine .
' Yes , Mum . I'm gonna do my best and I'll be the one who bring peace to Garderobe , for Sergay's sake and for yours .'
'Great talks Arika . Let's move on . Come on Mashiro , you too !'
' Yes , Sarah !'
Then , the three girls left the room . But before arika close the door , she turn and looking at Sergay's corpse , she said :
' Good bye , Sergay , I won't never forget you . You'll also be in my heart for the rest of my life .'
And on Sergay's corpse was put the Handkerchief that Arika did for the one who was support her grant's cost ..
