This was a fun read. The writing was pretty good, and I loved the humor. I’ll be honest, I’ve read a few Seija fics by now and personally I’ve kind of had had enough of the beaten and eternally difficult Seija, but I liked how she had moments to shine and redeem herself here, in her own unique way. The other characters were well developed too. The true ending **SPOILERS** was a bold move and not usually the kind we get, but hey, sometimes things turn out that way, and it was very strong emotionally speaking.
I really enjoyed the music. DDC has the best intro theme. The CGs and portraits were great. Neat use of sound effects.
It took me until I read the README to realize the Tsukihime inspiration (besides the Raiko school parts, which gave me Fate vibes). Nice job.
