Marisa is leaning to her house. She's closing her eyes, enjoying the ocean breeze and sunlight that warms her body. Her hat is off and her feet step on the rim to keep it from being blown away by the wind.
Next to her is Reimu who also enjoy easy time together with Marisa. This is what they do in this island, they have no enemy at all and can enjoy their days like what any yukkuri would dreamed of.
Reimu woke Marisa up when the sun is about to set. They give a last look to the beautiful sunset and then enter their house where their friends have waited for the communal dinner.
A Marisa entrusted with the “hunt” today give everyone their shares of sweets sweets. Patchouli who act like their leader told them anyone who still want more must go and get their own.
Marisa finished her food, but still wanted more. She look at Reimu who understand Marisa's sign, so they both go to Patchouli and told her they want to get more food.
Patchouli sent them to a hole in the middle of their house. The size of that hole is about the size of a yukkuri to pass through. After pushing themselves through, they arrived in a big cave.
The whole cave is made of the sweets sweets they eat every day. Even the tunnel are made of sweets sweets.
A Chen inside told Marisa to dig the sweets sweets from another corner while she looks restless. The curious Reimu then asked Chen, who showed Reimu a strange thing in the sweets sweets. The colour looks different.
After Marisa finished digging the food, she saw Reimu lick the strange thing.
Reimu exclaimed Happyness, stronger than the happyness this yukkuri family has been feeling everytime they eat. But the cave also shakes, scaring the three yukkuri. Marisa quickly take Reimu back up and they eat together after cleaning each others.
Marisa eats quietly, still disturbed by the quake. Reimu also eats quietly, but because she’s still thinking about the mysterious sweets sweets down there.
That night, someone exclaimed Refreshed!
Because they all live in the same house, it’s manner for the yukkuri to go out before getting refreshed. Hearing that, Marisa and Reimu can't hold back and they also got refreshed.
The next morning, Marisa came out of the house to see her own face reflected on the sea. She didn’t sleep last night.
Long long time ago, there was a Dosu. Standing more than 5 metres tall, she’s a mountain of yukkuri. Dosu is smart and understand human is dangerous. She bring her clan to the deep part of the forest and told them to stay away from human.
Being that big, human decided that Dosu is a threat and bring their weapons to kill her. Even though Dosu intended no harm, the human still want to kill her.
The yukkuri clan is split in two. First is the majority who believed Dosu should punish the human. The smaller group believed Dosu's teaching and want to follow Dosu to escape somewhere far from the human.
The first group attacked and instantly annihilated despite already being warned that they must run away when there’s that many human.
Human then chased Dosu who run away with the yukkuri in her hat. She opened a path through the forest. The human cornered her by a cliff.
Seeing her Dosu Spark is powerless, Dosu is pushed down to the sea. Instinctively as a Marisa type, she want to take her hat to float, but she remembered the clan inside so she sacrificed herself.
Assaulted by the salt water, Dosu closed her eyes. She hold her breath and miraculously, Dosu floats on the sea.
The clan is still trapped in the hat, unable to get out. While they’re safe from human, it’s only matter of time before they went insane by hunger and isolation.
One day, a Marisa found a hole in Dosu’s hat. While yukkuri respected accessories so much, the councellor Patchouli make a decision that they must make a hole to exit the hat. It’s very cruel to Dosu, but better than letting the whole clan died.
What they see outside is the sea. The yukkuri said, Dosu has become an island.
The clan’s Marisa floats with their hat and pick up sea weed stuck to Dosu's hair and bring them back for the clan to eat. There’s only a small number of them, so the food is sufficient.
But yukkuri had the instinct to breed, especially if their population are small. When councellor Patchouli allowed them too, the clan is soon filled with babies more than the food can afford. Sea weed is also became scarce.
Many Marisa never returned after they sail too far to find food for the family.
Councellor Patchouli felt guilty for this. She did “Please Eat Up” for the clan. After that, one by one the yukkuri left sacrificed themselves to let their little ones take it easy.
After even their parents sacrificed themselves, the children still eat up all of the paste and is now hungry.
It’s a KoMarisa who solved the problem when she found a patch of sweets sweets. The children realized they’re living on sweets sweets and start eating.
To keep from making big hole in their house, the children made a tunnel before starting to dig the cave.
This is how the current generation grows up. Everyday, a yukkuri would be entrusted with the duty to “hunt”, to dig the sweets sweets from inside the cave.
The rest of the yukkuri can take it easy either inside their very easy and safe home, or enjoying the sun outside.
Dosu is of course in pain from having to stay awake, holding the air in her mouth and then bearing the pain of having her paste eaten. The only thing that gave her strength is to hear that the yukkuri living on her is taking it easy.
At night, Reimu and Marisa is down in the cave. Reimu can’t hold back anymore, she said she wants to get sweets sweets for the little ones.
When her tongue touched the mysterious sweets sweets, she eats like being posessed by hungry ghosts. Even the quake never stops her and Reimu kicked away Marisa who tried to stop her.
Unable to bear the pain anymore, Dosu opened her mouth for a while. Salt water washes into her mouth and paste, hurting her endlessly.
Seeing that water suddenlyflood into the cave, Marisa runs away back to their home. Reimu whose pregnant is left behind.
Marisa is about to save Reimu whose feet is soaked and unable to walk anymore, but Marisa then saw Reimu breaks and throw away her own stalk. Consumed in anger, Marisa quit rescuing Reimu and leave her to die down there.
When arriving upstair, Alice has became raper by the shake and is raping everyone. Marisa survived because she jump onto her hat when the water floods in. Finally she got out of by biting through the top of Dosu’s hat.
Now, Marisa is alone, floating on the ocean.
