- FKG is collaborating with X-overd. Do the event you may get 3 SSR ticket and 1 SSR+ ticket.
That's give you 4 girls SSR rank if it not dupe. Or maybe you can get 1 UR.
- Hypericum reissue event is running so it's other more ssr girl for you. Try your best to get her.

X-overd is very easy read the guide in this community it will help you.
Even a complete newbie like me can do it easy.

Reissue event may hard for new start but with some good management
you may get the girl before event end. Good luck.

If you plan to paly fkg permanently, dont use dupe. Grinding and completing normal map to increase level and get free fg for gachaing. It will take few hours for you to be able to complete intermediate event map. Also dont forget farming weekly manyus to increase knight level.

Well. Like others said, try the cross over for 4 tickets and do the reissue for a 5* Hypericum.
Tuesday we will got the new event. I'm not sure what kind of event it will be but pray for one where we can get the girl before the end.
You also have the valentine log in bonus with a lot of FG to use.

If you are lucky, you can get 6 5* in less than a week.

And since you just started, you also can create multiple account (and use your invite link findable in your nutaku profile) and use your free FG on the gacha until you get good girls (maybe a 6*?).

And if you need a strong ally on the harder stages, I still have a free slot
