Suiseiseki was the third rozen maiden doll. She has a long brown hair, green and red eyes, and a green long dress. She has a twin sister named Souseiseki. Souseiseki is the fourth rozen maiden doll just like Suiseiseki she has a red and green eyes but she has totally opposite personality. Suiseiseki actions are like a fine lady but Souseiseki action is like a humble gentleman, despite of their differences they are totally close with each other.
One day rozen the doll maker talk to Suiseiseki secretly while Souseiseki talk with shinku. Shinku is the fifth rozen maiden doll, she acts like a noble person even though she acts like that deep inside she is a kind girl. Rozen talked to Suiseiseki to inform her that all of the doll rozen maiden must go to the human world. Rozen said all of the doll must have a medium for them to be alive and not to become just a normal doll. They also talk about the Alice game their father doesn't want to start the game because it's way too harsh he said to Suiseiseki there another way to become Alice without engaging the Alice game. Suiseiseki understand she herself oppose the game she doesn't want to fight her sister specially Souseiseki.
Before she go rozen said something" Suiseiseki I trust you and I believe in you this is the reason why I inform you with this information because I know you have the courage and wisdom to stop this fight. Don't forget as your father I'm very worried but as a doll maker I wish you good luck may the spirit bless you and your sister. If you have problem just open this locket and you can contact me" rozen said while giving her the locket.
"Don't worry father I know how important this mission is I'll try my best just to stop this game. I love you too father here to always remind you of us" Suiseiseki said while accepting the locket and giving her father a flower. As soon the talk was over she told everyone about what to do but she was careful with her so some of the secret won't be told. While talking shinku objected "why do we need to go to the human world" Shinku said "because that's what father ordered to" Suiseiseki replied" why did father told it to you not to me, I'm his favorite doll" Shinku shouted
" it's not important to whom father would say it what matter is we need to do what father want us to do and he made us all equal he love us equally he doesn't have a favorite ok?" Suiseiseki replied. Souseiseki defended Suiseiseki she said" that's right Shinku father created us to love each other not to fight and to obey what's father will. They ended their argument. Soon a dimension open and they entered they were separated except for the twins. The twins ended up in a forest fill with unknown creature. They stop by a big apple tree.
Suiseiseki asked" are you hungry Souseiseki?" Souseiseki replied" sort of" Suiseiseki pile up their brief case and climb up to reach for a bunch of apple. Souseiseki was worried and said" let me do that, that's dangerous" but Suiseiseki insist and said" don't worry it's going to be fine" and finally got to pieces of apple. She gave the apples to Souseiseki and said to her" you stay here and I will wander around this forest to find some branches to make a fire and to find something to cook so they can eat". Souseiseki said" I'll go with you". but she replied" you should stay here and guard the briefcase ok". Souseiseki said
" ok but if you're in trouble just shout and I'll go there as fast as I can" Suiseiseki said" ok, but you will do that to if you're in trouble". Suiseiseki enter the dark forest while she was walking she pick up some branches. On the way she just walked and walked and realizes she's lost. And it was dangerous because there was a storm coming. She said to herself" Souseiseki must be worried I need to go back there".
She summons her artificial spirit named Sui dream. She ordered to give her the watering can. The water is her weapon that can make a plant come out of nowhere and the watering can has the ability to nurture the tree of life of a human or can destroy it. She pours down the water from her watering can and a huge plant comes out. She can manipulate the big tree and make all the trees gives way and finally she sees Souseiseki fell asleep.
She was careful of her action so she can't wake Souseiseki. She gathered all the branches she collected and makes a fire out of it. She goes to a lake to capture some fish and cook them. But when she looks at the water she saw another doll but it was different. She was sure she never saw this doll before she was going to touch it but she pulled down the water. She shouted. Souseiseki wakes up and find her drowning she rushes down to help her and she summons her artificial spirit named lempincka and she ordered to give her the gardeners shear.
The gardeners shear has the ability to cut anything and it also can nurture the tree of life by cutting any grasses that surrounded the tree but it can also cut down the tree of life. As she gets her weapon she quickly cut the hand of the doll that pulled Suiseiseki down. Fortunately she got Suiseiseki she was planning to strike again but the doll was gone. While Suiseiseki was unconscious Souseiseki carried her to the tree take her clothes off to dry it up. She wraps her with her own coat so she won't get cold. Suiseiseki wakes up and said" what happened?" Souseiseki was glad that her twin wakes up and scolded her" Didn't I told you to be careful?" she replied" I'm so sorry; to make it up to you I'll cook some fish soup". Souseiseki hesitated and said
" I want you to rest, please rest." She replied
"ok but after I rest I'll cook for you, I think you're hungry". When Suiseiseki fall asleep Souseiseki hug her and said
"please be careful you know how important you are to me, where twins, we are one I don't want you to get hurt". Souseiseki also fell asleep. Few hours later Suiseiseki wakes up. And find her twins sleeping with her head resting at her right shoulder slowly she put Souseiseki to her briefcase. The briefcase acts as a bed for them. After that she wears her dress but she notices something her left shoulder has a symbol. That was a timer for her that's what her father said it signify how long can she remain she only has it because her Rosa mystica has a limit.
Her Rosa mystica is leaving her body because originally it is one with Souseiseki Rosa mystica but split by two. She kept it as a secret from her sister only her father and herself know. She put her clothes on so Souseiseki won't notice it she continues to cook. As soon as Souseiseki she serves the soup. They have dinner together. But a dimension open and pulled Souseiseki along and vanish quickly. Suiseiseki was surprise she tried to pull her back but it was too late. She summon Sui dream to open the same portal but she can't open it a force is blocking her. While Souseiseki wandered she saw a portal and enters it. She landed on a rose mansion. There he saw an old man.
As the old man turn around Souseiseki really felt sadness. The old man saw her and said "who are you?" she replied "I'm sorry I've got lost, I was travelling with my sister and I got lost.
The old man said "well do you need a place to sleep for tonight. Souseiseki replied "no need sir I want to find my sister". The old man replied "don't worry I'll help you look for her tomorrow right now I think you need a rest". Souseiseki has no choice but to stay. While Souseiseki told the old man what happened. On the other side of the world Suiseiseki was so worried she cried but she remembers rozen gave a locket so she can communicate with him.
Quickly she grabs her briefcase and gets the locket. She called her father. Luckily rozen answer her calls and said" Suiseiseki what's the problem?" Suiseiseki replied" Souseiseki fell down to an unknown portal, I tried to open it but a powerful force tries to block it." Rozen said "Suiseiseki you have the ability to open the portal but you need a medium to have enough power to unlock it. Go to Shinku her medium has the enough power to help you". she replied" thank you father". Rozen added" Sui did a symbol already appear to you?" she replied" yes father, don't worry I'm fine what's important is to find Souseiseki."
She ended the conversation with a simple good bye. She opens a portal that leads to Shinku. She saw how happy Shinku is with her new master. But she needs help. She crash through the window and accidentally hit the medium of Shinku. Suiseiseki rush toward Shinku and begging her to help her. Shinku hates Suiseiseki so she didn't help her.
