守りたい My Lovin' World (mamoritai My Lovin' World)
カヅチ「ごほん、あーあー、
今日からこの国は、あたしこと
健美カヅチに譲って頂くわ！」
ナカタ「どうしよう、このままじゃ
私たちの国、奪われちゃう…！」
譲れない物一つ 持ってるんだ (yuzurenai mono hitotsu motteru'nda)
それは託された約束 (sore wa takusareta yakusoku)
誰にも破れない 誓いだから (dare ni mo yaburenai chikai dakara)
二人こんなに もつれ合っても (futari kon'nani motsure atte mo)
シロウサギ
「ナカタちゃん！筋肉魔法少女に変身だ！」
ナカタ
「よ、よくわからないけど、やってみる！！
プロロ プロテラ プロテロりん！
負荷よ、かかれ！
マジカル・パンプアーーップ！
どう～ですか、この圧倒的筋肉美！
魔法少女、タケミナカタ！！」
カヅチ「へ、変身したって無駄よ！
力比べで私が勝ったら、
この国譲ってもらうんだからね！」
ナカタ「そんなことはさせません！
いざ尋常に、はっけよ～い！」
私のこの身がいつか (watashi no kono mi ga itsuka)
脳まで筋肉になっても (nou made kin'niku ni natte mo)
胸を張って 拳握って (mune o hatte kobushi nigitte)
振り絞った勇気が (furi-shibotta yuuki ga)
息苦しいくらいに (ikigurushi kurai ni)
熱くなる My Muscle Heart (atsukunaru My Muscle Heart)
カヅチ「あ～れ～！！」
シロウサギ「寄り切って
ナカタちゃんの勝ち～」
カヅチ「ちょっと何よこれ！？
話が違うじゃないのよ！！」
ナカタ「筋肉を制すれば神話も制す！
カヅチちゃんも一緒に筋トレ、
やりませんか？」
カヅチ「はあ～～！？？！」
ナカタ「ふんっ！」
私を包む贅肉が (watashi o tsutsumu zeiniku ga)
一人じゃ抱えきれなくなったら (hitori ja kakaekirenaku nattara)
私に魔法をかけて (watashi ni mahou o kakete)
揺るがない力が湧くように (yuruganai chikara ga waku you ni)
よりきって 突っ張って (yorikitte tsukidatte)
押し出されたこの身が (oshidasareta kono mi ga)
泥まみれになったって (doro mamire ni nattatte)
守りたい My Lovin' World (mamoritai My Lovin' World)
カヅチ「高天原中から来ました、
健美カヅチです。よろしく」
ナカタ「ええっ！？転校生って、
カヅチちゃん！？」
カヅチ（Na）「次回・筋肉魔法少女タケミナカタ
『ライバルは転校生！？』」
ナカタ「あなたのハートも、
マジカル・パンプアップ！」
English translation
I want to protect, my loving world
Kazuchi: "*cough*, um, uh, from this day onwards, this town
shall be given over to me, the great Takemikazuchi!"
Nakata: "What now, if this goes on our town would have been taken over!"
There is the one and the only thing I will not give up
That would be promises committed to me
Since I have sworn to let no one break it
Not even when the two come entangled together like this
White Rabbit: "Nakata-chan! Time to transform into the muscular magical girl!"
Since I have sworn to let no one break it
Not even when the two come entangled together like this
White Rabbit: "Nakata-chan! Time to transform into the muscular magical girl!"
Nakata: "I-I don't really get what's going on, but here goes nothing!
Puroro, Protera, Proterali
Witness this Magical Pump Up!
Witness this Magical Pump Up!
How's this? Such stunning muscular beauty
Magical Girl, Takeminakata!"
Kazuchi: "Hmph, that transformation is useless anyway!
Commence the battle of strength, and should I win
This town shall be handed over at once"
Nakata: "I would not let that happen
Come as usual and let the battle begin!"
Since whenever this body of mine
Has become muscles even to the brain
Stretch your heart, hold your fist, the courage mustered up
Could not have been stifled
It is heating up, my muscle heart
Come as usual and let the battle begin!"
Since whenever this body of mine
Has become muscles even to the brain
Stretch your heart, hold your fist, the courage mustered up
Could not have been stifled
It is heating up, my muscle heart
Kazuchi: "Oh~ no~!!"
White Rabbit: "With a Front Force-out, it's Nakata-chan's victory!"
Kazuchi: "Hold on, what is this supposed to be
This wasn't in the story!!"
Nakata: "When you conquer your muscles, you can conquer mythology too
Kazuchi-chan, why not do some muscle training together too?"
Kazuchi: "Huuuh~!??!"
Nakata: "Hmph!"
The heavy flesh that envelops me
Could not be held in only one person's arms
Cast that magic on myself
And let the unwavering force wells up
Force yourself forward, exchange your thrusts, the forward pushes served to this body
Had me covered with mud
I want to protect, my loving world
Kazuchi: "I'm Kazuchi Takemi from Takama-ga-hara High. Pleased to meet you."
Nakata: "Eeeh!? Kazuchi-chan is the transfer student!?"
Kazuchi (Narration): "On the next episode of Muscular Magical Girl Takeminakata,
'Rival as the Transfer Student!?'"
Nakata: "Let me also give your heart, a Magical Pump Up!"
'Rival as the Transfer Student!?'"
Nakata: "Let me also give your heart, a Magical Pump Up!"
