What a cutie!

Yami and Zoro noticed explosions going on in the castle on top of one of the mountains. Yachiru said "Mimi!" Yami turned around and she said "Let's go see what happened~!" Yami nodded and said "Enough for today." Zoro was breathing heavy and sheathed his swords with small cuts all over his body.

Yami looked at Yachiru and she jumped to his shoulder, shrinking down and slipping into his shirt, she smiled cutely and said "I'm cold~" Yami gushed and kissed her little head, saying "You are so unbelievably cute." Yachiru giggled and snuggled into his shirt, holding the collar and peeking her head outside.

Yami walked with Zoro to the mountain with the castle, telling Caroo to stay with the ship. Caroo saluted and went to sleep on the deck.

The trio walked up a cable and came to a giant castle just in time to see a fat man get blasted out from the roof and into the sky. Yachiru said "Wow!" Yami smiled and poked her stomach, she giggled and looked up at him, he smiled and she crawled into his scarf, poking her head out right under his left eye.

She kissed his cheek with her mini lips and smiled happily. Yami smiled and they walked forward, Luffy came out and said "Hey! You're here! Meet our new crew member!" he pointed at a reindeer, Yami looked at the reindeer and said "He looks soft." Chopper jumped in fear and hid behind a tree...but he only hid half his face the rest of his body was out in the open.

Yami was stunned and Yachiru giggled, Chopper realized and hid the correct way. Luffy laughed "What a funny guy!" Yami facepalmed and they started getting ready to leave.

A while later

The entire crew was running from an old woman, who was throwing weapons at them. Yami could've sworn she threw an entire shelf too, but nobody else saw that... Unfortunate.

They got on the ship and turned around to see pink clouds, snowing down pink snow, making the mountains look like Cherry Blossom trees! Yami was stunned and Yachiru mumbled "Pretty..." Yami nodded along and the crew sailed away, celebrating their new crew member.

Yami gathered everyone together and gave them all the Impurity cleanses telling them to use it in the shower/sea. They didn't question him at all, which surprised Yami a great deal. Luffy went into the shower and the rest jumped into the sea.

Yami was holding a bunch of ropes as the ship sailed and all their Impurities were cleansed from their bodies, washing away in the sea water.

A while later

Yami pulled them all back up and they scrambled for new clothes, Nami shrieked in the bathroom and came out with perfect skin, Sanji almost died looking at her. Literally. The entire crew was stunned by the effects of the Impurity Cleanse and Luffy was stretching even faster than before. He even looked better, what a blessing this Impurity cleanse was!

Yami explained "Basically, all the black stuff was the impurities in your bodies. It was all expelled and because of the one I gave you, you can't get any more impurities in your bodies. Meaning, you can eat forever and never get fat, your skin with be pure always, your body is in an optimal state to be worked on, meaning you can get stronger, faster. You'll never get sick either."

Yami lifted his shirt and said "You'll be muscular as well... Well, except the females. Basically, you maintain a 'perfect' form." he looked at Chopper and said "Though, I don't know what happened to you, Chopper." Chopper said "My coat is sleeker and stronger than before. I also thinned by a bit."

Usopp looked at his abs and shouted "I HAVE ABS! WOOOOOOOOOOOOOOOOOOOOOOO!" Sanji kicked him and said "Of course you do, moron. Didn't you hear what Yami said? It makes us more handsome." he flipped his hair and Luffy said excitedly "Stronger? Faster?!" he wrapped his arms around Yami and hugged him saying "You're the coolest mystery demon I've ever seen!"

Yami blinked as Luffy rubbed his cheek on Yami's cheek, he coughed saying "Please get off me." Luffy cheered "No!" Yami just sighed, Vivi looked at her skin and said "Wow~" Zoro flexed and said "How much faster?" Yami replied "Around 4-5x" Zoro whistled and went to the back of the ship to train.

Yachiru took the girls and talked about a bunch of things happily, she had friends that were girls, she was too happy. Yami gave Chopper and extra vial along with a Healing potion, he also gave Chopper a silver token and said "I stole a bunch of these from my dad."

Chopper held the token and said "What does it do?" Yami said "Turns your bones into metal. The metal is non-poisonous and I haven't tried it myself, but I assume it will take on the properties of the devil fruit that has been consumed prior or following the transformation." Chopper's eyes widened and he shook the token saying "Is this magic!? Who's your dad!? A famous scientist-magician?!"

Yami blinked and replied "Something like that, I guess." Chopper waved the token in his hands and mumbled "Metal bones could increase attack output by 3x at the minimum..." he looked at Yami and said "Do you have more?" Yami tapped on his earring and fanned out a bunch of tokens, Chopper gawked and said "How do you have so much?!" Yami replied "My dad collects a lot of things and leaves them lying around at home most of the time. I happened to slip into his storage space one time and stole a bunch of things..."

*Flashback*

Little Yami with his backpack was sitting on Hiro's lap. Hiro replaced himself with a shadow clone and Yami fell into his shadow somehow ending up in a space with a ton of items stacked up with labels. He blinked and started stealing things for himself.

Metals, Woods, Metal Bones, Merge tokens, Impurity Cleanses, Healing Potions, Stamina Potions, Mana Potions, etc. He took everything that looked cool or interesting to him, not all of them obviously.

He skipped the scary looking token, chests, tokens with an arrow on them, and a rock. The books and scrolls didn't interest him either.

Suddenly, he was ejected and back in his spot, falling to the ground. Hiro caught him and said "Where you going, kid?" Yami blinked and hugged his backpack, Hiro shook his head and put Yami back onto his lap. Yami yawned with Hiro and they both fell asleep again.

*Flashback over*

Chopper was stunned "Just lying around?!" Yami nodded and Chopper mumbled "That's pretty crazy... How do I use it?" Yami said "Just crush it on your chest." Chopper nodded and walked away with all his new things.

Yami went to sit down and yawned before hugging his sword and falling asleep, leaning his back against the railing.

*Part 3! Give mooooore!*
