Passport Usage Count and Review

The passport usage count was indeed 10 times. It was set at 5000 cat toys and a high price, but considering you can use it 10 times, I think saving up cat toys to challenge it is definitely a good option. However, some souvenirs from the places you go with the passport don't have an aura, so if you want to collect souvenirs with auras, it's better to aim for the otherworld.
