Here, I've found the original Japanese:

Spoiler:

Episode 12: Eternal Engagement (Kanji are for "never ending contract")
Yuuta is uneasy over Rikka's disappearing. While he is worrying, he is told why the Wicked Eye was born from the second user of its power. Knowing the truth behind her power, Yuuta heads out into the town to search for Rikka. The story of the Dark Flame Master and the user of the Wicked Eye is concluded.

Staff is correct.

Edit: also found a comment from the main female cast.
-Tell us what to look forward to in the climax of Chuunibyou.

Spoiler:

Asasaki (Nibutani): For me it sums up to "Who will take the blow for the loveable Deko-chan?"

Uchida (Rikka): In the second half of the series, you feel that Rikka and Yuuta's story seperated from everyone else, but in the remaining two episodes, everyone's hearts become one again. Look for that point.

Asakura (Kumin): Up until now, everyone's been doing their best in their own spots. In episodes 11 and 12, everyone's thoughts come together due to a development. Everyone properly sees each other, or perhaps they start to notice each other and understand anew. Kumin doesn't have any chuunibyou past and previously she watched over everyone's scuffles with warm eyes. I hope everyone looks forward to the scene where Kumin starts to become active, showing a new side to her, and everyone starts to think in a Kumin-style way to understand the situation.

Uesaka (Dekomori): While I think the development that ties Yuuta, Rikka, and everyone together is amazing, for me, my impression of Dekomori greatly changed as I performed in the 11th episode. And then it changed again in the final episode. That's my highlight. Is Dekomori a pet? A little sister? For everyone who equated her with a tiresome brat, I hope you in particular watch what happens!
