It does have an odd atmosphere at the end, feeling like a last chapter. This chapter covers the ending of Volume 2 of the LN, well except for the one part that wasn't included.
Spoiler: If it makes y'all feel better he does get kidnapped later using his one weakness.
And now we enter into worst part of the story. Prologue and half of Volume 3 will be some what like this. That let me reevaluate 'Clingy Female' archetype in anime... in a worst way. Imagine any scenes of male 'pick up artist' trying to force girl with them, from now on i can't unseen that.
Wait, gluttony is really dead?
What a waste of good design, i thought she will join his harem becus she's in cover... It also feel anticlimactic, she just gone, reduced to atom without anything like his mark absorbing her mark or something
