It's a 5* ticket with small chance (7.5%) for 6* girl.

Ticket itself has no expiration date, but we don't know if it will get restocked in the future. Medal exchange has expiration date and will get restocked usually once a month. Try to get at least the 5 cheap medals before shop reset/restock.

Meanwhile I dunno which girl to bet on this 2nd race, gonna play it safe.
