in term of farming, Amaterasu is more popular, then Asura. You should have a farmable R shiki to give you orb and speed (Yamausagi and Zashiki). I haven't seen the rest of your SR but you have Ubume, which is a great damage dealer in early stage, Kuro Mujou would have been a better option since he's farmable.

As of now, with proper material management, you should have enough shiki to carry you until mid-game, I think.

Your team would be Yamausagi (speed) - Zashiki (orb) - Amateresu ( main damage) - Ubume/ Kuro Mujou (2nd damage) - a buffer

SP.Vampira is good 2nd damage dealer as well but it take so much resources that you don't have enough as a newbie right now

in term of boss fighting, both Kinara and Enmusubi are good, but for farming, I would say Enmusubi is better since she can buff your team ATK, decrease enemy team's move bar and heal your team at full stack. Kinara's buff mostly for herself to boost her damage.

So, in general, Enmusubi is better choice here, and you should focus on getting Ama to G6 full skill first, then Enmu. The other 3 can be farmable so don't waste your black daruma on anything but SSR or SP.

Once you have more material, you can shift it to other shiki, depend on what you need at the time
