Funimation has announced that their rights to seasons 1 and 2 of Sekirei will expire on February 9th, after which, the anime will not be streamed or reprinted.
They describe the 2008/2010 adaptation of Sakurako Gokurakuin’s fight manga:
Minato had no luck with the ladies until a warrior babe named Musubi fell into his life. Hunted by a pair of twin sisters, Musubi was searching for the right guy to unlock her hidden powers. Minato fit the bill, and now he’s caught in the middle of a supernatural slugfest where voluptuous vixens take turns beating each others’ clothes off!
The 2004 manga ended in 2015 after 18 volumes.
