Congratulations on clearing E-3 Hard as well! ^-^

I happened to only score 2 boss kills/S ranks in E-3 as well, final kill also included. It was quite tough, but nothing compared to E-4 final kill... :/

Ship locks are indeed quite tight in this event, especially regarding fast CVLs. I only have my Ryuujou left available for E-5..

Good luck with E-4! You probably need it. :O

PS. I have just added my "guide" on the first phase of E-4. It should probably be pretty easy for you. =)
