[Used Can]

Here's a summary I got from: http://jbbs.livedoor.jp/bbs/read.cgi...1306918807/l50

Spoiler:

The chapter starts with Lala fixing Nana's device. Then they remember when they were kids and they helped Lala catch a device of hers that had gone haywire. Then the talk about boobs start and Lala tells Nana she had come up with a device to make tits bigger. She uses the device, but it seems to break and smokes comes out, engulfing Momo and Nana. When the smoke is cleared, Nana had huge tits and was happy about it, then we see Momo and she was flat. Nana started teasing Momo, but the effect eventually faded out and they returned to normal.

Later on, we see Rito and Momo in Mikado's office talking about Lala's devices and Oshizu serves them tea. Eventually, Mea shows up and asks them if they've seen Nana and Momo tells her she's out to buy some stuff. Mea goes out but comes back and greets Mikado. Mikado acts suspicious about her and Momo asks her if she knows about her. Mikado tells her that even if she's a doctor from the Darkness, after the Organisation Yami belonged to got destroyed, she hasn't heard anything about it nor about Tearju.

Later we see Ren who approaches Rito and hands him a sample CD Run had left for him. As soon as he hears Run's name, his heart starts pounding. Then Ren tells him Lala is very nice to him and that he should return that kindness. Basically, he tells him he should be more serious and leaves. Rito takes Ren's words to heart and he thinks he should be more serious and that he should tell Lala he loves Haruna. That's the correct thing to do, and that Run wouldn't forgive him if he kept on being indecisive. But then he thinks about Momo's harem plan and an image of Lala, Haruna and Run all nude is shown. Rito thinks of himself as stupid for considering Momo's idea.

Afterwards, the scene is at the Yuuki's house at evening and Mikan tells Rito that dinner will be served soon and to call Lala and the rest, then she has a Newtype moment and tells Rito to be cautious of Momo. Rito then goes to Lala's room and tells her dinner will be served soon and Lala's says she'll go downstairs as soon as she's done with her device. Rito asks her why she's always working on devices and Lala tells him she likes doing that because her childhood at the palace was boring. During the war there was nothing to do, and when peace came, there were only adults and the only child that showed up was Run and that wasn't very often. She said she liked playing pranks with her inventions.

Then Momo listens Rito and Lala's voices coming from Lala's room and she thinks they may be on to something and imagines them kissing, but then says that's impossible since Lala is like a child. She decides to eavesdrop and Nana asks what she's doing. Momo asks her to be silent and they eavesdrop together. Rito and Lala are talking about the twins and Lala talks about the incident with the device that was talked about the beginning of the chapter. Then Peke shows up and said that wasn't Lala's blunder, but that she did it on purpose to kept her sisters from fighting, since back then all they did was fight. Nana and Momo had no idea about this and thought Lala had always took care of them. After that talk as over, Rito thought that Lala seemed to have done the same before. Then he and Lala ended staring at each other and Rito's heart started racing fast and he thought he had to tell Lala about Haruna. Lala asks him if he's okay because he's red. He backs away because she was too close and accidentally hit a device with his foot. This device is a rope used to tie things and work as a crate. So it lifted Lala grabbing her tail and ended up throwing her on Rito upside down.

Afterwards, we see the twins in the roof. Nana said she was happy Lala was their sister and Momo agreed thinking Lala wasn't as childish as she had thought.
