You can ask and dare the Yu's about anything, just no inappropriate or sexual
Yuri: And kissing each other is out of the question
Yuto: Sorry, but I would have to agree with Yuri on this
Yugo: we Yu's are just good friends with each other
Yuya: There's only a brotherly love between us
P.S.
NO user can ask the SAME dare or question twice.Example:
User 1: asks to go on a date with Yuto(User 1 CAN'T ask to go on anothet date with Yuto)
User 2: CAN ask to go on a date with Yuto
Edit side note: since Arc V has been out for awhile Zarc is NOW AVAILABLE for asks and dares.
