Steins;Gate episode 9
Service angle + tsundere queen = win
This is exactly the kind of rape-face I fear when encountering someone in a dark alley
So it is not revealed whether Ruka was disarmed or not. Feyris seduces Daru into telling him about the Phone Microwave. Sending the mail to Ruka’s mom (Eat more veggies) had one astonishing effect: The IBN 5100 was never found by Okarin. Kiryuu Moeka also behaved very strangely. My guess is that she, like Okarin, can retain her memories after a world line change. That would explain her paranoid nature when it comes to taking pictures of where she went and what she did as proof. It’s probably not of much use when the world line changes. Imagine remembering things that actually never happened. It would drive you crazy.
On a side note, Makise Kurisu is a tsundere tensai hentai 2ch shoujo.
So Okarin tries to find the IBN 5100 again and asks Feyris for help. Feyris is revealed to be the daughter of the man who owns all the land around Akiba. Furthermore, Feyris was the one who was asked to bring moe-culture to Akiba. She agrees to help Okarin under the condition of letting her send a D-Mail first, 10 years into the past. But Feyris refuses to let Okarin read the message she wants to send. He, after some arguments, finally agrees to let her send it. The world line changes once again. Okarin realizes that they might’ve done something that cannot be undone. Shortly after that realization, he notices that Akiba isn’t an otaku fortress anymore.
Personally I think Okarin is too naiive. He is too careless as to how many and what messages can be sent to the past. Minor changes can become huge changes given a larger timeframe. Basically, letting someone send a message back in time without knowing the contents is really stupid. Telling someone not to go somewhere on a specific day may cause them to never meet someone they were supposed to meet, which could lead to things like certain people are never born or similar stuff. You can imagine how great the changes that are derived from this one little thing can be.
