Although King and Diane are obviously weaker than Dolor and Gloxinia, hope is not all lost for the duo as they may be able to defeat Demon King's servants. It is uncertain at this time whether the battle between these teams will favor King and Diane. However, if the pair is able to cast an extraordinary attack, they may emerge triumphant once the battle concludes.
Chapter 199 of "Nanatsu No Taizai" is entitled, "Those Without Light," and some believe this pertains to the Nazguls which are regarded as Ulairi in a specific language. Fans over at Manga Helpers are speculating these creatures being referred as Nazguls are Gloxinia and Dolor. Though "Nazgul" is a terminology used in "Lord of the Rings," the two characters are believed to be servants of the Demon King.
It can be recalled in the previous chapter that Gloxinia was able to catch up with Diane and King who were running inside the forest. With Dolor, Gloxinia, Diane and King all face to face, fans are predicting a battle will ensue among these four characters. Who emerges triumphant is still unknown as of this time, but "Nanatsu No Taizai" followers believe that Diane and King's powers are way to inferior compared to their opponent.
Despite their handicap, fans discussing at Manga Helpers believe that battle that would comment would benefit both Diane and King. According to user Demonspeed, the fight will not totally be one-sided, favoring only the stronger team. This was agreed by Baum as he believes Diane and King's abilities will improve from this experience. Meanwhile, several of the users are also guessing the battle will be cut short, and a conclusion to their fight will not be reached.
On the other hand, fans at Manga Skip also matches the same predictions, saying that both Diane and King are certainly inferior to Gloxinia and Dolor's power. However, the author said he is quite unsure whether the battle would contribute something to the growth of the former duo. But he is keen in declaring that Diane's physical strength are weak in all categories compared to Gloxinia's abilities.
