Shangri-La Frontier manga volume 5 features story by Katarina and art by Ryosuke Fuji.

The fight against Wethermon has been a brutal battle of attrition. Entering the final phase of the boss fight, Pencilgon's team is battered, but not broken. While Sunraku goes one-on-one with Wethermon, Pencilgon and OiKatzo team up against Wethermon's mecha-steed. Most of Pencilgon's items have been depleted so the prudent course of action would be to play it safe and try to survive the theorized ten minute phase. However, Sunraku is built different and decides to challenge Wethermon head on!
