It was rather good, but if you don't mind, I'd like to point out that your french was incorrect. Jai- or rather j'ai, as is proper- means "I have". I think you were looking for Je: the pronoun "I". Otherwise, the story was rather enjoyable!

ALUCARD YOU BASTERD!

lol this is great i really like it i hope you do more

That was pretty good, nice an' short, but not too short for a oneshot.

is this before or after Pip joins Hellsing?

Nice PxS-ish story there... althrough Pip`s accent is a bit much sometimes and the ending was... well, a bit sad.
But other than that... not bad at all.
