At the start of the battle, it looked like Bushiki and Cristina would be able to hold the horse monster off for an hour without any problem. But after 10 minutes passed the horse monster suddenly changed its approach and started to fight more seriously.
If at first it was fighting with 20 percent motivation, then currently it was fighting with 100 percent. It was shooting bolts after bolts of black lighting toward Cristina while kicking Bushiki non-stop. Bushiki tried to fight back by using her weapons to attack the legs of this monster but even all out attacks by her were able to deal a minimal amount of damage and even those damages healed soon afterwards.
