For the rift plane, see The Inferno.
The Rare Nevi in The Inferno is the second rare nevi in a rift plane in Gravity Rush. It is the second hardest rare nevi to defeat. Similar to the other rare nevi, it also shares the special green coating and is immune to Kat's special attacks.
After entering the Inferno, you will need to slide down the wooden bridge path until you get to an open area. After defeating the various nevi here, a tunnel with fire surrounding it will open up. Go through this tunnel until you get to yet another open area. In this area, if you go to the bottom you will find an isolated train track and it leading into a small tunnel. Follow these tracks through the tunnel to the other side where the rare nevi is located.
For this rare nevi it is recommended that you have your gravity kick upgraded to at least level 4. This nevi is actually not very complicated to beat. While standing at the entrance to the area in which it is located, at the edge of the tunnel, shift towards a point just above its right shoulder; it will execute its punch, giving you a significant window of time in which to attack the cores on its back and flee. Merely repeat this process and it should fall before too long. However, do be wary of the shielded core on its face which takes quite a few gravity kicks to destroy, even at the highest level.
This Rare Nevi is a green Giacago. It has all of the abilities of the original Giacago but is a much stronger, durable, and faster (attacking) version of it. Unlike the original Giacago, however, the rare version is green and has a protective shell covering its face.
