I know ist been 12 days since this post lol but do you know how I get the Hitlan to leave, and also how do I can start the himari route?
Do you mean Hitman? he can leave with the help of one of the girls i think but you could also use "Le Gun" from the safe in Josef room . The password can be found in the Starmaker comments, Himari has little content (1 scene as far as i know) that can be unlocked by getting the Heavenly Husband trait by beating helping the blonde punk you meet during Wednesdays
The password for the safe is 7172
The blonde guy appears in different locations and you must answer correctly on 3 separate events
