A little bit more in detail:

1. BCJP will not appear in Android device playstore even if you searched it using the JP name and texts if your playstore is not set to JP region first. However, you can find BCJP in webpage playstore version instead but you still can not install it. To install BCJP directly from playstore so it is registered for auto-update, you need to set the playstore to JP region (ie: get JP VPN > reset playstore data >  connect to playstore to refresh reset region) and install from there while connected to JP playstore area.

2. Ask PONOS as the developer, not us. We are not and do not have any connection at all with the developer.

4. 10x does not mean guaranteed uber rare. Guaranteed uber rare has its own event period. As explained in Gold duck's reply. Basically, the gacha roll has three kinds of events: Discounted roll for catfood price, increased chance for uber drop (3x chance becomes about 3% to 10% chance) & guaranteed x10 roll get 1 uber rare event. Rolling the gacha outside those events is considered as waste usually.

5. Why not? PONOS needs money to run the company. If the players can get everything for free easily, PONOS won't survive. The number of free catfood given by Battlecats monthly is considered very high already in ratio with the difficulty to obtain free catfood compared to other games.

6. Merc Storia has released officialy in full version to JP and Chinese market. English merc storia? Still beta and not many players yet. So it is not worthy to bring the collab to EN version.

7. Yes

8. Yes, it is quite rare. As others said, the drop rate is hetween 20% to 30% (although data mining claims it was the 20% drop chance)
