The story:
The show opens up with our MC, Chizuru Shiina, being mocked for being a teacher's pet. She has a crush on this hot teacher and decides to stand up for herself in the hallway against some mean (and poorly drawn) bullies. A fat ugly teacher attempts to stop her and the very handsome teacher grabs his arm. Now malding and horny the fat ugly bastard plants evidence of a crime in the hot teacher's desk and using this evidence he blackmails Chizuru into having sex with him. After forcing Chizuru through a few sexual act's episode 1 ends. In episode 2 the ugly bastard forces Chizuru through even more embarrassing sexual act's.. and that's it. In episode 3 even more wacky sexual acts ensue but this time the ugly bastard wins a horse racing bet, that's cool right? In episode 4 Chizuru is forced through more public sex, and that's it. In episode 5 we see Chizuru finally fed-up with the ugly bastards tormenting and she tries to confess her true feelings to the hot teacher and be finally liberated from the torture.. and then she finds out he has a girlfriend. Feeling betrayed she does.. what is somehow the norm in hentai.. and goes back to her tormentor because he's the only one who cares for her. On paper this doesn't sound bad and honestly is good but seeing as this is the ONLY development the character gets it really doesn't add all too much. In episode 6 we see Chizuru meeting Chii-chan from Chii-chan Kaihatsu Nikki and they both get fucked and accept their cum-dump status. That is 6 episodes summed up in one run-on paragraph.
The art/animation:
This is a Lune production under their Bunnywalker label that is animated by Studio T-Rex and directed by Raika Ken. The character designs were done by Suzuki Takato and look good, unfortunately the art itself is quite smudgy at parts and doesn't look good even in some major key-frames. As for the animation itself it looks great, as is custom from T-Rex shows. It is based off the doujinshi by Muchakai and it looks extremely similar, which is nice.
Sound:
Good voice acting for the most part and a cool intro sequence with cool sounds. Not much else to say on it other than the ending song is quite generic.
Overall:
Chizuru-chan Kaihatsu Nikki had the seeds planted to be a good blackmail show but unfortunately just doesn't utilize the characters beyond two episodes. Just a few more scenes of the characters interacting, and I'd probably have given it above a 5/10.
