Kaiju No. 8Manga’s Ending Soon Aligns With The Recent Developments Of The Story
Kafka Hibino Finally Achieved His Goal
Kaiju No. 8manga, inching closer to its climax, although a surprise since the manga has only 110 chapters so far, aligns with the recent developments of the story as Kafka has already fulfilled his promise of standing by the side of his childhood friend and superior Mina Ashiro, finally achieving his goal of the two battling together. Additionally, the special move Kafka had honed with Soshiro Hoshina, the Third Division vice captain, is about to be revealed in the intense fight against Kaiju No. 9, which is already in its last stage.
The Last Wave arc already feels like the endgame of the series, and with the confirmation that the story’s reaching its climax, this could mean that Kaiju No. 9 may be the final enemy in the story, paying off for all the buildup this threatening Kaiju has gotten so far. However,Kaiju No. 8fans can still expect some fierce fights to go live, as Kafka and the Defense Force’s fight against the Kaijus is not an easy one to win, so the author can still introduce another powerful enemy before the end of the manga.
