Narita Boy

Story related, can't be missed.

You've entered the red house, you've learned the Dashstab move and received the Train ticket and you've spoken to 'The Glove' who has given you the key to 'The Ancient Portal' where Johnny is being held. Climb the platforms of the ruins into the 'Ventilation Corridor' and then exit to the left into 'The Red Hall'. Jump down and go to the left and interact with the terminal to open 'Access to the Portal'. Fight your way through the 'Antechamber' and go through the door and enter the portal. You'll arrive at the 'Stallion Coliseum' and where you'll simply walk up to Johnny and rescue him.

Now with Johnny on your side, prepare for battle! Activate your newly acquired wild fire because the enemies that spawn at the start are all weak to fire. Once you've defeated them the real battle begins versus 'H.E.X'. H.E.X is a pushover. All you have to do is slash him and dodge through him, then slash him, dodge through him over and over again. You just need to watch out for where he goes haywire and electricity covers him, but that's about it.
