Bretman totally slayed it as the main character Inosuke Hashibira, complete with his boar’s head mask and katana.

Cleo, on the other hand, looked super-cute as a mini Nezuko Kamado with her pink kimono and hair bow.

Cleo is the daughter of Bretman’s younger sister, Princess Mae.

Bretman and his little bestie also took a hilarious pic as “Monster’s Incorporated” characters Boo (Bretman) and Sully (Cleo).
