Disclaimers

Hogwarts, the Magic World, most spells and creatures, and most of the characters (the more awesome ones) belong to J. K. Rowling, creator of Harry Potter. And one of the most awesome authors ever. I'm so sorry for ruining your characters. v-v
....
The Marauder's Map was not created in reality when this story took place, I know. That part is innacurate. It was created in the Marauders' either sixth or seventh year. The Marauders just became Animagi in their fifth year and made the Map a year or two afterwards. See Harry Potter and the Prisoner of Azkaban.
...
I also know the Lucius Malfoy's seven years older than the Marauders. He graduated the year they came into school. But you have to admit, the fights are worth it.
....
Plots, Fou-Bing Bokuseiinzenmoninari, Deenu Ramento, Kokoro, Chugi, Nermid, Bing-Fou Bokuseiinzenmominari, Tujoshimo Jan'ro, most of the idea on Japanese/Asian magic world belong to Neko Shin'rai(Me!)

Half of this plot belongs to all my RP buddies that have ever RPed Harry Potter Past with me as Sirius and Remus. Thanks, guys. ^-^
