[Sixth]

Spoilers from Teh Ping:

It's about Minami and Mizuki relationship with Akihisa in the novel

Spoiler:

Likely in this season: Test of courage, Minami faints from her phobia of ghosts, causing Akihisa to carry her out. Mizuki shouting at the two idiots from the OVA for berating Akihisa. Mizuki wanting Akihisa to call her 'Mizuki', which Akihisa felt was weird.

Not likely in this season: Mizuki lives with Akihisa for a few days as her parents were stuck in another country. Minami trying to win Akihisa over with her cooking, only for Miharu to foil her every attempt. Minami and Akihisa (and the gang) in Minami's house, preparing for exams. Only Minami and Akihisa are left, as Hazuki doesn't want Akihisa to leave (until she slept). Akihisa went to Minami's room, sees the plushie he bought for Hazuki and a photo on it (thinking that it was a gorilla, but it was actually him...), Mizuki going shopping with Akihisa during the time she stayed with Akihisa. Both girls wanting to get a two-people-three-legged race with Akihisa (in front of the FFF. They failed, he went with Muttsurini) and Mizuki thinking that Minami would molest Akihisa...

Some bits here and there. Nothing really concrete...except for the home stay. Oh, Akihisa meeting Mizuki's parents.

Akihisa and Yuuji Vs Class F+Class C+ Class D + Class A

Spoiler:

It's class F betraying Akihisa and Yuuji because everyone found out that Akihisa and Mizuki were living together. Yuuji got involved because of that braided hair girl who (from Akihisa's response) thought that Akihisa like Yuuji, thus FFF wants to purge all homesexuals...note that the girl's name is called Tamano Miki from class D. Remember nii episode 3, the girl Sugawa tried to confess to? That's her. She likes her Aki-chan, which means, Akihisa in cross-dressing, so not Akihisa himself. She just plays a minor role though. These events happen in volume 8, it's hilarious seeing class F (everyone except Hideyoshi) + class C (they were in the midst of a summoning battle) + Shouko team up against Akihisa and Yuuji, with rampant rumours that Akihisa managed to conquer Mizuki, Minami, Miharu, Kubo, Hideyoshi, Aiko, Yuuko, Miki, Yuuka (class rep of class C), and it took Hideyoshi to fake voices through the PA system to stop them.
