There's something that bothered me. We know from earlier episode that the anime still obeys the 'only 6 toudans can be sent to the past' because unit 1 needs to be pulled out first before saniwa can resend unit 2.

So when saniwa pulls Kanesan and Mutsu to Hakodate with him, I assume that Yagen, Tonbokiri, and Tsurumaru got sent back to citadel, so in return he can send Yamanbagiri, Oodenta, Hige, and Hiza to Hakodate. BUT Horikawa is still staying in the past. He stayed in the past in the time span from the burning of Satsuma residence until Hakodate war, working his way up until he became Hijikata's helper or whatsoever. That means there are currently SEVEN toudan in the past.

So it's either Horikawa can defy saniwa's call and chose to stay in the past or the '6 toudan only at a time' is not absolute.
