Is blood C in anyway related to blood plus? if so can آپ tell me how its realted and if not can someone tell me what the story is about?

Blood c I think is about one of divas daughters.and blood a is about a trip saya and haji takes before she goes asleep again and goes beserk at vietnam.And blood yakou Joushi is about haji finding ways after she goes beserk and is asleep,right before blood plus.it goes "blood A","blood yakou joushi",then "blood plus"(better to watch عملی حکمت first then read manga because its easier to follow in my opinion.),and finally "blood C"

there is also an عملی حکمت movie fromm 2000 called"blood the last vampire"

blood plus russian rose manga happens after haji leaves that پھول for saya at the end of blood plus.
