Sekirei, Vol. 9 (Sekirei, 9)

A party to determine the #1 Sekirei!
When the ark slumbering beneath Kamikura Island shuts down, a foreign military force seizes the opportunity to launch an invasion! Meanwhile, musubi is busy dealing with a delusional Karasuba, who desperately awaits the return of a friend who is never coming back...Things take a turn for the worse when the Jinki start melting down, sidelining the Ashikabi and leaving the beleaguered Sekirei with their backs to the wall. With hope seemingly lost, who will rise to challenge the "Sekirei Queen" and the "overseer of Kouten" waiting high above......?The final battle is here, and it all comes down to the last Sekirei standing!!
