I screencapped the mofo out of the short To Heart 2 commercial that happened to be on after the end of Akahori Gedou Hour Rabuge. Thank you l33t-raws!
The short minute or so trailer has basically all Konomi shots though we do also get to see her two friends and the main male character. Mostly Konomi talking about the season and entering high school with the opening/ending song playing in the background. Tamaki, of course, does get in a line or two too 
Primula gets her time to shine to the cheers of lolicons everywhere!
Cleverly “accidentally” finding a rip on her beloved neko doll, Primula heads to Rin’s school to show him the problem. Using her lolicon powers, Primula gets Rin to chase after her after giving him the “I want you now” look also using the rain to her advantage to show off her developing assets. Slowly falling under the powers of loli, Rin enlist the help of the other girls to get Primula some underwear. Unfortunately for him this only leads to a lot of embarrassment and blue balls.
Eventually after the girls play sexy underwear dress up with Primula, they choose some normal wear while Rin goes to find some cosplay clothes neko plushie to give to Primula. Either having fallen under the influences of lolicons or trying to look good in front of the girls, Rin’s perfect gift to Primula makes her extremely happy in more ways than one.
No doubt Rin will be getting lucky with some girl tonight!
Just another normal day in the life of Rin. Wake up calls by Kaede, chased around by fan clubs, preparing for exams, eating Nerine’s eggs, etc etc. When Kaede collapses due to exhaustion, however, all hell breaks loose as Rin tries to cater to Kaede with the help of everyone else while she gets better. One would think being a little pampered would be a good thing, but apparently Kaede’s sole existence is to be by Rin’s side serving him hand and foot.
Good thing she decides to seduce him to keep that fact clear.
Exams are over as some of the girls get used to high school life. Nerine takes the opportunity to score some brownie points with Rin by taking a page out of Kaede’s book by learning how to cook. Unfortunately unlike Kaede, Nerine isn’t adapt to cooking as she is to randomly blowing up buildings for the sake of Rin.
So Nerine can’t really cook! Not a big deal! Rin my very lucky friend, she already loves you, is pretty hot looking, can destroy at will, has big breasts, and probably is one hell of a demon in the sack! An excellent choice no matter how you look at it!
Rin’s harem is finally complete just as exams rear their ugly heads to joy of all high school students. Inbetween running away from the various fan clubs, flirting with Sia while studying, and taking exams Rin has to rack his brains on how he met the girls originally.
I mean, it always help to know the backstory of the girl you’re trying to bang right?
