It turns out that the secret experiments that the Kudou Family has been conducting was for developing parasite dolls, a female combat robot possessed by a parasite. Experiments on the dolls' operations are being conducted at the Steeplechase Cross-country venue, where security is abnormally tight - so much so that Tatsuya himself can't even break into the premises. As such, Tatsuya orders Pixie to keep an eye out for the parasites while he conducts adjustments to the CADs and gives instructions to the underclassmen as an engineer. However, this continual sense of nervousness and nonstop days of hard work are tiring out Tatsuya. He's never felt this tired before.
Like I promised, I'll keep my mouth shut
about the cover-up and your backroom dealings.
كما وعدت، سأبقى مُتستّراً حول طمس الحقيقة
وتعاملاتك في الغرف المُغلقة
Über die Verheimlichung
und Ihre Machenschaften
Como les prometí, no diré nada
sobre su fachada y confabulaciones.
Como os he prometido, no diré nada
de esta tapadera y vuestros trapicheos.
Comme promis, je garderai le silence
sur vos petites cachotteries.
E come promesso terrò chiusa la bocca
Como prometi, vou ficar quieto sobre a
ocultação de informações e seus planos ocultos.
Как и обещал, я сохраню в тайне всё,
что вы натворили и о чём умолчали…
