No clever setup for this episode.
We joined Iroha asleep while a radio show played on her phone. As the DJ read the above caller’s question a creepy girl’s voice took control of the phone, glitched it and laughed creepily.
Next morning Iroha somehow transferred to a school in Kamahana. She messaged Kaede about it but no response. Other girls invited her for bento but she wanted to search for Kaede.
Iroha looked up Rena for her whereabouts. Ever since what happened in the Post ED of Episode 5 Kaede distanced herself from Rena and Momoko. To change the subject Iroha asked her if she heard of any recent rumors.
First was something about an Invisible Girl. The way she described the rumor hit home with Iroha, girl who kept to herself so long she eventually became transparent to people ultimately turning invisible. Another rumor involved some place called “Endless Solitude”. More on that later.
Later Iroha visited Banbanzai and was surprised to see her daughter there. Felicia agreed to quit being a mercenary to work at the restaurant for free food. Tsuruno talked about another rumor, “Electric Wave Girl”. It’s about a strange voice that can be heard on the phone standing under the radio tower. Supposedly the voice was of a girl calling for help.
Back home Iroha saw her future wife talking to someone. She didn’t get all of it but I’m sure she heard her discussing the Wings of Magius with the girl on the phone.
The next day after another Ui and Friends dream and the mysterious radio show broadcast complete with creepy girl laugh, Iroha’s new teacher informed her of a troubling situation. Felicia got into trouble and asked for her to come pick her up at the station.
On their way home:
Felicia: Hey Mommy, aren’t you gonna ask me about why I got into trouble?
Iroha: Are you still doing mercenary work?
Felicia: No! I work at Banbanzai now. Some girls were saying mean things about my new mommies so I beat them up.
Iroha in her head: That’s my baby!
Felicia wanted to investigate the radio tower. They tested the rumor by making a call. The caller wasn’t asking for help but did laugh creepily.
The next day Iroha’s classmates spread false rumors about her because she got called by the teacher the day prior. Not worrying about it she visited Rena again who had more info about “Endless Solitude”. Iroha got spam messages (She’d been getting several throughout the episode). She erased them but this time they saw one that asked whether Iroha was a mahou shoujo followed by a call for help. Iroha rushed over to the radio tower and made sure to leave a message for Yachiyo.
On her way to the tower she spotted one of the twins. She tried tailing her but was spotted, summoning the above Doodle to attack.
Iroha had a hard time but thanks to a “mysterious” rescuer the Doodle was stalled long enough for the cavalry to arrive and destroy it.
We end the episode with Mrs Tamaki, Mrs Tamaki, Cousin Tsuruno and Felicia Tamaki answering the spam. We’ll see what curse will befall our superheroine family next time.
