Story start with Koharu looking around in cafeteria and meet Manpukumaru that’s busy stuffing her face. Manpukumaru notices her and calls Koharu, Shadow Moon-chan, because her name is Tsuki(moon)kage(shadow) Koharu. Manpukumaru also said that her name is cute, so Koharu let her call her Shadow Moon-chan. Then Echigoya shows up. Koharu ask Echigoya what’s today’s special menu. Echigoya said that Koharu is better off asking Manpukumaru about that. According to Manpukumaru, today’s special is curry. Manpukumaru said that today’s curry is so delicious she can’t stop drinking it. Koharu is bewildered by the use of ‘drinking’ here then Manpukumaru said that her kokoro no shisho / bosom teacher taught her that curry is drinks. And then Manpukumaru ask for seconds while Koharu exasperatedly said that there’s still so much about world that she doesn’t know. While helping Manpukumaru cleaning the mess she made while eating, Manpukumaru shout that it’s time for BuBuBu and ask Echigoya to turn on the radio right away. Koharu doesn’t know what is BuBuBu.

Once they turn on the radio, Koba- I mean Viola’s voice came from the radio speaker. Viola ask the listener are they listening to radio while sitting ‘seiza’ and said that radio show brought to you by Valkyrie Drive Bhikkhuni broadcasting club aka BuBuBu bringing hottest information from all around Bhikkhuni is starting. Viola calls herself Viola-sama. The radio is 30 min and viola said that anyone that won’t listen carefully will receive a beat down from her. Then casually mention Echigoya as the show sponsor. Then Mana appear to advertise one of Echigoya product at discounted price. A sunblock cream that’s usually sold for 50 point now only cost 15 points! Then she tried it on but as she opens the caps a putrid smell assaulted her nose. Mana continues by saying that there are other cosmetic product with unknown origin sold at incredibly cheap price and she recommend it for people that aren’t afraid to lose their life as long as they can get it cheaply. Then Echigoya is flipping out saying she didn’t gave them that kind of script and protested that with that advertisement there’s no way anyone would buy her stuff. Koharu calm Echigoya saying you reap what you sow. Manpukumaru silences them saying she can’t hear the radio.

Next segment is guest segment, starring Kagurazaka Rinka and Ranka. Rinka stutter while trying to introduce herself and Ranka is overactive. Viola then hit Ranka to calm her down. In this segment Viola will read some of the question listener sent and ask Rinka and Ranka to answer. First question, after watching Rinka’s wonderful proposal this girl can’t help but sigh everytime she remembers it, then she ask Rinka how did she do it so wonderfully, is it the food or daily habits? Viola sounds so disinterested and said that she's much more wonderful. Rinka is apprehensive about telling the asker her three sizes and Viola answers it for her. It’s 179-179 with bosom as big as a drum can. Her favorite food is tree sap, so if you wakes up early you can find Rinka eating her favorite food on the tree. The things she usually concerned of is whether the plate on her head is dehydrated or not. Then Ranka cuts viola off by destroying the table. Ranka said she won’t let Viola tarnish Rinka’s reputation using petty tricks. And proceed to reveal Rinka’s real three sizes, 93-57-84, a H-cup. Her favorite food is bread with cream filling and her current dilemma is finding a country where she can marries her little sister. Her strong point is her cuteness and her weakness is that she’s too cute. Rinka ask Ranka how did she know the precise number of her three sizes and ask what’s this about marrying little sister. Ranka thought Rinka was embarrassed and tell her to just declare it to everyone that they love each other. Then Rinka starts talking about how she love rabbits fluffy ass and that she’s doing her best learning medical treatment. Viola stops her there and continue with second question.

Second question ask how the sisters got to Bhikkhuni. Viola said what kind of question is that and said that it’s okay if they don’t answer it. Rinka is okay with answering the question. Before coming to Bhikkhuni they only heard rumors about V-virus. They heard that if they caught the virus, a part of their body or even their whole body will turn into a monster and start attacking people. It’s only a rumor but it’s still frightens people. Ranka add that she and her sister discover that they both have the V-virus by pure luck and said that it’s a miracle that no one found out. People that got contracted by V-virus and can’t control them have very high chance of going berserk and start attacking people. To calm down those people that going berserk from time to time, Rinka and Ranka Drive to fight them. Ranka said in hindsight it’s probably because they fought against those people that going berserk that allows them to control the V-virus.

Anyway, they were doing well, no one knows who they are and some even thought of them as Hero of Justice. Though one day, a contracted person went berserk and took a little girl as hostage and then barricade herself. Ranka said she tried to stop Rinka from going because people from government will arrive soon. In the end they drive in front of the special team designed to handle Valkyrie berserk cases like this and got taken into custody. They solved the case, both the berserker and the little girl are safe. But the people around them look at them like they’re some kind of monster. Only the little girl that they save looks at them innocently while giving them a smile. They were brought into a research facility and they run some test on the twin. When their parents come they thought that they were being released but their parents only said “you two are sick, you need to get yourselves treated”. Ranka thought of destroying everything and then runaway somewhere but then if they let the disease left untreated then before long, even they could go berserk. Ranka said that they know that they are monster, but no matter what she doesn’t want to betray the smile of that little girl that they save. Rinka add that perhaps all of the girls in this island all have painful memories, some of them might have experienced something far more horrible than what happened to them. Nevertheless, both Ranka and Rinka believes that thought they are sick, they are not monsters. Sickness can be treated, they come to Bhikkhuni to prove that. Then Viola conclude it with ‘lets combine our strengths and work hard on the treatment program.’

Ranka said that not all bad things happened to them. They got to make new friends and appear on radio show. Then Ranka got very excited and Viola hit her again, saying that a local radio show like this would never made them famous enough to be an idol. Viola thanks them anyway for telling their story. That’s is for this segment. Before continuing, thy move back to Koharu&co. Manpukumaru is crying a bit and ask for more curry because she’s a bit sad. Next corner is joke corner. The guest have to answer Viola sexily. The guest are Mana and Momo, they introduce themselves as Mana the wicked and Momo the murderer. Mana ask why they should introduce themselves like that while Momo questioned Viola why is she doing this and depend on the answer she might need to kill everyone. Viola answer that this is something related to V-virus treatment and Momo easily bought it. Uh the next section is pretty hard to translate cause it’s about puns. I’m pretty bad at puns so I’ll just gloss over them. First joke is about oppai and groping puns. Second joke by Mana is about Viola and Koharu pushing boobies together and Viola boobies turns out to be fake. Viola is pissed at Mana saying that her boobs is 100% real and push it in Mana’s face. Last joke is well.. it’s uh.. revolves around Momo and Mana. Momo is saying something totally inappropriate here but because they censor it.. yeah, I’ll leave it to your imagination. Viola then ends the radio in cute Engrish.

It ends with Manpukumaru laughing and Echigoya freaking out about the possibility getting scolded by the Principal for sponsoring BuBuBu. Lunch period then end and they all went their separate ways.

Whew. What the hell that wasn’t a summary, that’s almost word to word translation of the drama CD. It isn’t word to word translation of course. Anyway I’m gonna be brief for second part, sorry.

Story start on beach because Echigoya calls them. Thanks to the radio fiasco, bad rumors about her store stuff start to go around and the Principal scold her. Viola said that the radio show actually made a new record but she did feels a bit guilty for the bad publication Echigoya receives. Momo and Ranka aren’t listening and talk about Momo wearing muffler while in swimsuit. Yes, all of them are in swimsuit provided by Echigoya. Echigoya then goes off saying that the Principal gave them one more chance to prove themselves that they can make a proper radio broadcast with no risqué material. If they failed the radio will be cancelled. Momo said to leave it to her, in the next broadcast she will make even more sexy remarks. Echigoya is exasperated and continues with her agenda for today. All of them will star in new radio broadcast, including Manpukumaru. It’s about them having mini athletic meet.

Koharu protest saying the swimsuit is embarrassing. Echigoya then proceed to have monologue about how she prepared micro cameras to capture the girls figure and that the swimsuit she provided is actually is a melt-when-it-touches-water-swimsuit. Echigoya is prepared to sell the picture she captures today to whole world. First competition is flag competition. They all race to get the flag and then deliver it to Echigoya. The winner is the girl that manage to safely deliver the flag to Echigoya. The winner get one year free Echigoya’s new dessert and Echigoya’s cosmetic of dubious origins.

Mana is leading the race but then Viola slide attacked her only to have Momo kancho’ed her. Manpukumaru then get the flag but Rinka and Ranka stand in her way. Manpukumaru then pass the flag to Koharu but both Viola and Mana stop her. Koharu hides the flag inside her swimsuit and Viola is raring to check her body out to get the flag. Viola grope Koharu. Manpukumaru feels guilty for passing the flag to Koharu and Drive with her. Koharu now have Manpukumaru as weapon and prepares to payback all the groping Viola did. Viola, Rinka and Ranka runs away to the sea then their swimsuit start to dissolve. Koharu is going out of control and start attacking things randomly. Momo appear and said that Echigoya should have leave it to her from the very beginning. Echigoya promises to pay Momo any amount she wishes for and Momo accept the job to stop Koharu. Then Momo kancho’ed Koharu and Koharu loses her consciousness.

When Koharu woke up, Echogoya is gone, taken away to the Principal office and everyone on the beach is naked. Koharu remembers nothing about Viola groping her or Momo kanchou’ed her. Koharu only remember seeing a dream where all of them happily playing in the beach. Turns out, Momo’s kanchou actually have effect of blurring the line between dream and reality for the victim. Then they all go back to their daily life of continuing the treatment program.

The story supposed to ends here but Viola and Mana appears again to tsukkomi them saying that are they really gonna end the story nicely like that, Viola answers that if she questioned it she lose.
