Shakugan no Shana Season 2 Episode 16

The festival ends without any more disruptions, and it seems that everybody forgot about Konoe. Before Pheles left, she gave Yoshida a secret Hōgu. She wants Yoshida to use this cross shaped Hōgu when something strange is happening to Yuji. It will summon Pheles, but to do so, the human who uses it will disappear due the limited power of existence. Yuji requested to get the sword Blutsauger as a weapon to fight.
