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.
