The dark shinobi engages Ikaruga in battle and overwhelms her with her array of weapons before taking her leave. Later, Ikaruga is informed that her brother, Murasame, who she replaced to become the shinobi successor of her family, has gone missing. Later that night, Ikaruga encounters Murasame in her room stealing her sword, Hien, but she manages to send him packing easily enough. After being ejected from the household, Murasame is met by Hanzou, who reminds him that being a shinobi isn't the only way of life. After receiving some advice from Hanzou, Ikaruga decides to start giving Asuka summoning lessons, managing to help her get over her fear of frogs and learn to use her summoning art. (thetvdb.com)
