My song, my life full of passion...I want to convey them all to you, who I have yet to meet. Release the Altereactor! Idol☆Glo at full force! Limit breakthrough...to the next stage!!!

Bond 2	アイドル至上主義の特異点へと迷い込んだのは いわば『劇場版』のえっちゃん。 ノーマル状態よりもちょっぴり感情豊かで活動的、 そして作画コストが高い。 作詞・作曲、歌唱に演奏、バトルパフォーマンスと よくばりなシンガーソングフォーリナー。	NA TL NA Localization: The one who wandered into the Singularity where idols reign supreme was, in essence, the theatrical version of Ex. She is a little more emotional and active than the normal version, and it costs more to draw her. She is a singing Foreigner who wants it all, as she handles the writing for both music and lyrics, singing and performing, and even fighting in battles! Fan Translation: The one who got lost in the Singularity where Idols rule supreme is, so to say, a "Theatrical Release" Ecchan. Compared to her normal state she is more emotional and energetic, so the cost of animating her is expensive. With composition and lyricism, singing to perform and battle performance, a sing-a-song Foreigner who wants it all.
Bond 3	さらに元をたどるならば “謎のヒロインX〔オルタ〕”の原典は、ユニヴァース界でそこそこの人気を博したリアリティ番組から。 謎のヒロインXとコンビを組む『第１期　学園編』と ヴィラン連合に帰従しつつ ダーク・ラウンズの復活を志す『第２期　ヴィラン編』。 『劇場版』はその中間の特別エピソード。 ひょんなことからユニヴァースいちの アイドル・サーヴァントとなるために頑張るが……？ まあ……ほら……ですね、 銀河系をシンバルにして攻撃する月面歩行ロボとか、 インフレにもほどがあるじゃないですか。	NA TL NA Localization: But if you want to go further back, the original Mysterious Heroine X (Alter) originates from a reality TV show that was somewhat popular in the Servant Universe. In season 1, the School Arc, she formed an alliance with Mysterious Heroine X, while in season 2, the Villain Arc, she was a part of the Villains Coalition while striving to revive the Dark Rounds. The story in this theatrical release is a special episode that happened between these two seasons, wherein certain circumstances have led her to try being the Universe's top idol... Well... Okay, yeah. One can only tolerate so many stories about galactic battles against moon-walking space robots... Fan Translation: But if you go back to the origins, the original source for "Mysterious Heroine X (Alter)" is from a Reality Show who gained popularity in the Universe World. Forming an alliance with Mysterious Heroine X in "Season 1 - School Arc" and subjugating the villain group by aiming to revive the Dark Rounds in "Season 2 - Villain Arc". The "Theatrical Release" is a special episode in between those. Curiously, she's doing her best to become the number one Idol Servant of the Universe because...? Well... it's... you see, things like moonwalking robots that attack the galaxy with cymbals, there's a lot of inflation too isn't there?

Extra	バーサーカーのヴィランであった自分と比べると、 ひょうひょうとした態度や口調には あまり変化は無いものの、その心情は軽くほぐれ、 自然に微笑んだり、自分から冗談を言ったりもする。 人を喜ばせ、楽しませたいという気持ちが前面に表れる。 その反面、他人に見せまいとしてきた弱さやいらだちも 思わず見せてしまう。 剣を振るうにはただ邪魔でしか無かった心の揺らぎ、 そういった感情が自分にもあったのだと驚き、 作詞や作曲に活かせれば面白いかも…… と気づき始めている。 ヴィラン（悪役）として恐怖と暴力に頼らず、 歌や音楽によって人を動かせるのならば、 自分に素直になってみるのもいいかもしれない……と。	NA NA Localization: Even though her aloof demeanor and tone of voice haven't changed much from her villainous Berserker form, she has loosened up a bit. She even smiles now, and sometimes actually makes jokes. Her desire to please and entertain others has surfaced, but she also allows her weakness and frustrations to show. She was surprised to learn that she had many emotions, which were simply in the way when she was just wielding her sword, and has come to realize that these feelings could be applied to writing music and lyrics. She is starting to realize that, instead of relying on terror and violence as she did in her villain days, maybe she should be more honest about her own feelings if it means she could move people through song and music...
April Fool	アルトリアサーヴァント なぞのヒロインXオルタが アイドルにへんしん したすがた。かっこかわいい もちうたもある。かつてはやみぞくせい だったかきらめくステージでじょうかされ いまではひかりぞくせいだ。	Altria-Type Servant Mysterious Heroine X Alter turned into an idol, and her signature song is both cute and cool. Her attribute used to be darkness, but the dazzling stage lights purified her, and now she is a light attribute.
