I wrote Manipulamon Reins a lot like an adventure story. I wrote this book very much like a Shonen series, with "moar powuh!" moments and overcoming enemies with determination, and learning the new technique, and the long fight that lasts the entire narrative, and all of those familiar tropes. In a Shonen story there is always that moment when a new threat arrives and the heroes hit him/them with the thing that beat the last guy and utterly fail. That's what this chapter is. Maybe it's a spoiler, but in this chapter InfernoKnightmon, the guy who tanked a hit capable of burning through an impenetrable wall, and then killed a living extinction level threat with a single attack, is barely a match for Tyranterramon, who isn't at full strength yet. This is the chapter where the heroes realize that they will have to reach a new level of power to defeat their foe. They just have no idea yet what that is, since their previous "next level" doesn't do the job.
