The author said that when two S's meet, there must be an M [dirt].
So, when Kamui met Okita Sougo [not Wei Chong, but BG], Ogura Nen appeared.
However, Ogura Nian is not a tsundere or a bitch, she is just an ordinary girl who unconditionally obeys the orders of her superiors and occasionally makes trouble for her deputy commander [is this ordinary?].
As the saying goes, a sailor who doesn't want to be a captain is not a good cop [die].
Therefore, Ogura Nian's dream is to become the number one person next to Sougo, Dou S and Okita III, the Shinsengumi Emperor [what the hell].
But the author also said "Why don't you die yet", where there is a male protagonist, there must be a male supporting character.
In fact, the Kamui in Ogura Nian's eyes is really just a middle-class sissy [who is really going to die].
This article will be updated every week but not necessarily how many times. The author is lazy and has many pitfalls in the late stage of cancer, so you don't have to look forward too much [I told you to die].
