To ensure Junko could monitor the game from the outside and not raise any suspicion, Mukuro disguised herself as her sister and pretended to also be a victim forced into the killing game. she maintains a more upbeat "valley-girl" style persona, such interjecting "like" and "totally" into her sentences and speaking in a more haughty demeanor. She's friendly, albeit pushy, and even claimed Makoto is an "omega male" due to his passive nature.
