Ren agrees to take Mana around to see the town, but she's anxious about and uncomfortable around Monster Strike.  When Ren gives her a MS ring, however, she gladly accepts it, thinking it's an engagement ring.  When she realizes her mistake, she runs off in shame... and that's when a monster makes it move.
You've come to take my 
protective power, right?
Ihr seid doch gekommen,
um meine schützende Kraft zu erlangen.
Vinieron a quitarme el poder, ¿verdad?
Venís a quitarme el poder, ¿verdad?
Vous venez voler la force
que je protège, n’est-ce pas ?
Sei venuto qui per conquistare
il mio potere difensivo, no?
Vocês vieram para tomar 
meu poder protetor, não é?
