I cant believe she was holding back the entire time.

These guys are monsters and laxus is just a whole new level. When he starts imitating/quoting Natsu things get epic. But no one can test erza for endurance, not from the first time we saw her and not now.

I believe Minerva's magic is not Spacial magic because how it seems she uses it. I believe it's more of a summon magic where she has to use an object connected to the person in order to deliver her magic to their proximity. For example: In the fight versus Lucy she took her keys but before all that it was pretty much all melee. When her keys were in her hand she started to deliver hit magic to Lucy.

This is same with Erza. First think Minerva did before attacking Erza was picking up Erza's sword and severally injuring the Mermaid girl. After that, she started that magic against Erza.

In this recent chapter Erza says she figured it out and was instantaneously in front of Minerva. This suggest to me Erza, though fast but not light speed fast, used her Equip magic in connection to Minerva's Summoning magic.

I do not feel right to call it Spacial magic because all we know it can be called Realm magic, and that Spacial is independently mustered instead of having a physical object in connection with said target like some Voodoo doll.

Just my 2 cents ><
