I know that back at the Miburo Y.G. we discussed the years in which
some members of the Shinsengumi were born in. Refresh my memory was
S.H. born in the Year of the Dragon 1844 many calculators don't go
that far back? And we'll probably never know what year Okita was born
in since there is conflicting info on how old he was when he died.
