Luffy saw the weird mirror alone in that room. If he was a caution wizard he would be careful, in the wizarding world there were tons of cursed objects that drove hundreds of wizards to insanity or death, but this was Luffy so he just went towards the mirror and stood there seeing his reflection.

''Uh…is nothing much.'' Said him.

As he continues to stare at the mirror, he saw something different. It was him, but he wasn't with his Hogwarts rope, he was with a large red shirt and instead of using pants he was wearing shorts, something he misses.

''Is that me?'' Asked Luffy seeing himself in the mirror

He soon saw more people coming, it was his friends.

''Nami, Zoro, Sanji, Usopp and Robin?" Asked luffy seeing the group all together smiling and having fun.

However, it didn't stopped there, soon appear 5 more people in the reflection. A tall muscular man with blue hair and no pants, a dead looking guy with an afro, a fishman, a girl with blonde hair and a rabbit like face and another woman but this one tall and with appear to be horns in her head.

''Who are those people?" Asked Luffy.

He didn't know that he was looking at the Erised mirror, an object that would reflect on the person most desired part of their hearts.

As Luffy continued to observe his reflection, his mirror self soon pointed out towards something. A giant boat with appear to have a flower or a lion face.

''I have a boat?!'' Scream Luffy amazed at that.

Soon the boat raised it flag and Luffy saw what appeared to be his face, but as skull and his straw hat was still there.

''I am a pirate! Oh my this is awesome.'' Said Luffy all amazed at.

The young wizard greatest desire was to be the one with most freedom in the wizard world, while in land you are obligated to obey all the rules, in the sea you are as free as you can bee. Luffy didn't know why this pirate path, but he would keep that in mind.

''This mirror sure is funny.'' Said Luffy smiling.

Soon the mirror luffy showed something that was in his pocket, and it was a giant piece of meat.

''Meat!'' Scream Luffy going to go after the meat, but he hit his face on the mirror.

Pow

''Ouch, so is not real? Ok I got.'' Said Luffy trying to put himself together.

As the wizard tried to see more of this vison, his mirror said something towards him.

''I am king of….' Said the mirror Luffy before he vanished.

As Luffy saw this he was confused. He didn't know what was that or what was the meaning, but it was cool so he didn't thought much about it.

He decided to just keep that in mind, so he decided to just keep cool and relax for the moment. Just as the school started to whisper something in his head

''Snape…dealing…danger. Come back'' Said the whisper

Luffy was now nervous, he wasn't armed with his wand, and he wasn't in the best shape to fight. Best thing to do was go back to his dorm.

''I better return.'' Said him to himself.

Soon Luffy put the sheet back to the mirror, so it didn't appear as someone was there. He ran all the way towards his room, while someone using a cloak was reaching that room.

At the Gryffindor dorm room

Luffy saw his owl was also in his room, so at least she was safe for now.

''Hey Collen, you are ok?" Asked Luffy to the owl.

The owl keep chanting and Luffy knew what she wanted.

''You want this?" Asked him taking out some bread crumbs out his pocket and give them to his owl.

Soon the owl was having a great day eating her lunch and soon she decided to fly for a minute.

''See you later!'' Said Luffy waving to his owl.

''Who are you talking to?" Asked Sanji

''I just let Collen flight out a little bit.'' Said Luffy

As Luffy kept his encounter with the mirror mostly to himself for now, because he wanted to wait for his friends to return to talk about this experience, he was just thinking of all things that he would have to talk with them in order to continue this ´´Philosopher stone´´ quest.

So, this is official the end of the first semester at Hogwarts for Luffy. It was some ride for him, don't worry the rest is about to come and the quest is about to get tense. Unlike some other One Piece x Harry Potter stories, Luffy and the others will get some action and not everything will be about Gryffindor. Well, this my take, thank you all.
