Thanks for the kind comments! It genuinely means a lot.
The ward system DID expose her as succubi, let me quote MC from this very chapter for you: "I modified the wards to be particularly potent against succubi".
In the previous chapter, Halo warns Filia against touching the ward to avoid electrocution. Given the succubus's proximity to it, we don't know if she got fried by the ward or its circuitry. Halo had suspicions about her being a succubus, but I believe she was more concerned about accidentally murdering a child.
I'm still a novice using MTL, so many things (including logic and reasoning) could be inaccurate or inarticulate. Hopefully I'm doing okay enough, but I would expect her actions make more sense in the original work (even if they are foolish).
Thanks for the TL
How long until we catch up with raw?
I'm worried about harming the original work, so I don't intend to ever catch up with the raw. The translation is currently 8 chapters behind, but I'd like to be around 10 - 12 chapters behind (2 volumes - 1 year). I plan on slowing down releases for a while to ease into that range. Anyone is more than welcome to snipe the translation though.
