|Episode 9 - The Board Chairman's Memories are Painful|
Wikipedia summary: <spoiler /><spoiler>
Yozora messages everyone to dress in swimsuits for the day's club activities. As the members arrive, they find Yozora dressed up in a swimsuit with a horse mask. After playing around with the horse mask, Yozora explains that she wanted to make use of her swimsuit while avoiding crowds. Sena offers Yozora her private beach house as a way to alleviate the concern of crowds. Labeling it as a "training camp", the club accepts. The next day, Sena calls Kodaka and asks Kobato and him to come to her house and meet her father Pegasus Kashiwazaki and butler Stella Redfield. Kodaka and Kobato arrive just in time for dinner. During dinner, Pegasus talks bad about Hayato Hasegawa, Kodaka's father, but Kodaka tries to tell Pegasus otherwise. Next, Kodaka and Kobato are offered rooms for the night as the last bus for home has already left. While Sena takes Kobato for a bath, Pegasus offers Kodaka a drink. Pegasus talks about having drinks with Hayato in the past and gets drunk, falling asleep on Kodaka's bed. Kodaka looks for help but bumps into a naked Kobato running away from a naked Sena, who notices Kodaka and runs out of the house. The next day, Kodaka lies that he was too drunk to recall the events of the previous evening. </spoiler>
My comments: <spoiler /><spoiler>
The first part of this is just blatant ecchi pandering, with everyone wearing swimsuits in the club room and Yozora having a full body swimsuit and a horse mask...
Then Sena invites Kodaka and Kobato over to her mansion. Sena's dad is ashamed of his first name, Pegasus...
I wasn't expecting this at all... Pegasus and Kotaka's dad (Hayato) apparently know each other. Kotaka gets mad when Pegasus calls Hayato a scumbag. Kotaka's dad wasn't ever mentioned at all up until now, except for that one flashback scene where the dad told Kotaka they were moving.
Sena's dad gets shitfaced drunk with Kotaka, while Sena and Kobato take a bath together.
The lewdness levels in this episode... I keep mistakenly thinking it can't possibly get any lewder, but it keeps going.
