People in their mid-20s taking mental damage...RIP sensei and also kind of 'ironic' considering MC is like over 100+ in age....Yeah MC still acting like a teenager (She sure as the mentality of one...) and treating anyone in their mid to late 20s as old people XD
Though at least MC is enjoying Sensei's blood now instead of her initial taste of sensei....Guess emotion and current feelings of the target's blood can be affected by stress and negative emotions....Plus the mood and atmosphere probably affect taste as well lol (Kind of like candle lit dinner and the appearance, smell of food can subtly affect the food taste to your tongue.)
Yura is pretty much the only sane person there in the harem, Wakana is basically the head-kin/Minion and leader of the harem...Basically promoting and kind of running things (Escalating things for the MC even) and Sensei just got caught up in this due to her snooping but end up being happy to be there in the group due to finally having friends to have out with (Was too much of a nerd and focus on school work to hang out).
Yeah, Wakana being a little bit jealous there, hopefully MC rewards her a lot of head-pats, hugs and gentle biting lol
MC is also getting carried away with her ego being boosted by Wakana and getting cocky until she finally meets Vampire hunter....We all know MC is going to be freaking out and struggling when the meeting happens despite MC's super natural abilities but hopefully Wakana can help save the day in the end and add the vampire hunter Nun to the harem XD
I guess this is why Vampires don't want to be making too many kins, minions...They get caught and imprisoned for over 10,000 years by vampire hunters like that random vampire Carmilla (Ruruna's pet bat even claiming and warning MC about annoying human rights law when MC talk about how biting other is a vampire's instincts lol).
