Tsubasa: RESERVoir CHRoNiCLE, Volume 7: 06/26/15
Volume 7 of Tsubasa: Reservoir Chronicle by CLAMP ends the Oto story arc, introduces more of Syaoran's past, and throws in new enemies.
The ending of the Oto arc pivots on the same dream-state / reality conundrum that leads up to the Rô piece of the companion series, xxxHolic. Oto isn't what Syaoran et al believe and as they've entered under magical means they haven't been privy to the truth.
The big show down though brings these false pretenses shattering down. The man behind much of Oto's strangeness is tied to Syaoran. And that connection between mentor and student reveals further layers of subterfuge between reality and the current state of things.
Behind all of this though, are a man and a woman, shown watching the events from some undisclosed location. They are set up as being in opposition to Yuko. While I realize they are probably the "big bad" for both series they come off as clichéd.
My biggest problem though with volume 7 is the vast amount of pages wasted on the "woosh bang" swirling fights between Syaoran, his ex-mentor and the others on the team. Lots and lots of sword swipes, swirling dust and other pointless theatrics.
