So I have cleared D21, but I haven't unlocked F46(reward Kikka) not F47(reward Ne engine)

Anyone know some quest that is requered to unlock these quests?

Also I have heard that you may need to get LBAS at world 6(F43) to unlock the prototype Keiun quest, so is there anyone that unlocked F46 or F47 and haven't completed F43 because i haven't completed F43
