The great Jahy is inspired to train her body so she can go up against the Magical Girl.
While she does various drills with the boss, the latter casually drops the training once she reaches her weight loss goal.
Reaffirmed that finding the mana crystals is the best and fastest way forward, Jahy redoubles her efforts there again.
That's when a grade schooler passes by and offers Jahy help.
I swear it as the Dark Realm's 
second-in-command!
!أقسم على ذلك كوني الثانية في القيادة في مملكة الظلام
So wahr ich die Nummer zwei
des Dämonenreichs bin!
¡Por mi honor como la número dos
del Reino Oscuro!
¡Por mi honor como número dos
del Reino Oscuro!
Je le jure
sur mon honneur de nº 2 !
Lo giuro sul mio buon nome di seconda
in comando del Regno Oscuro!
Aposto meu posto de
segundo no comando!
Не будь я вторая в мире демонов!
