Team Mafia or Yakuza {Osomatsu-San X Reader}

Long ago the sextuplets had divided into war between three older and three younger of the Matsuno brothers. It all started by fighting over a girl... You were just a normal girl with a normal life until you found out your older brother, Adrian, has been working for a secret Mafia gang called Kuro Yin (Black Yin) and their enemy yakuza gang, Shiro Yang (White Yang) came to fight to get you join their side. However you fell in love with a special NEET. Who will you join and who will you fall in love with?

Please bear my grammar mistake cause ELA isn't my best subject, but I do enjoy writing stories :>

[ I don't own any characters from Osomatsu-San but the fanfic ]

I recommend watching the anime if you enjoy comedy and watching 6 NEETS in their whacked up adventures.
