Might add character descriptions later, for now you will have to be satisfied with images of the main characters (From the VN)
(Edit: drat, beaten to it by a siscon ..)
(Edit2: Added character descriptions ... as much as my memory serves me anyway
)
Haruka - the male protagonist. Wouldn't really know where to start describing him, as Haruka doesn't really have any traits that stand out (Aside from his physical features sharing similarities with Sora). Your average well-meaning guy who now shoulders the responsibility for his and Sora's immediate future, as their parents died in a car crash just before the start of the story. On the upside, he isn't overly dense either, and gets things done if he sets his mind to it.
Sora - Haruka's twin sister. Having had weak physical constitution ever since birth and the limitations that imposed on her lifestyle during childhood, she hasn't really developed a taste for human relationships. Rather spoiled and lazy, Sora has rather anti social personality and is more annoyed than anything else towards whatever activity that would require effort on her part, social interactions included. (She is extremely abrupt even when it comes to Haruka ... others typically just get an angry glare
) Favorite (and only) pastime includes browsing the internet on her laptop, locked away in her room. (I bet not what many people expected personality wise
)
Akira - Local shrine maiden, though her personality is different from what are used of the archetype. A very friendly and outgoing person, Akira is well liked by just about everyone around her. A bundle of positive energy, she is a person that is generally happy with what she has and takes pleasure from little things in her everyday life, brightening up pretty much any scene she takes a part in. Befriending and helping out others is a second nature to her. Very close friends with Kazuha, and a good friend of Ryouhei, whom she forms a quirky comedic duo with.
Nao - Haruka's neighbor and someone he had befriended during their earlier visits in this town, though it has been a couple of years since their last meeting. Somewhat big-sisterly, it is rather obvious she cares about Haruka a great deal, and is rather helpful when it comes to Haruka's first days in this rural town and his adjusting to the new environment. Other than that, i don't really have much to say about her character, as she lacks any distinctive quirks. A fairly ordinary appearance in all aspects, and in my personal opinion, the least interesting character of the bunch.
Kazuha - tsundere fans rejoice, for Kazuha is there to fulfill the token role in this title. Daughter to a rich family (though she doesn't seem to think much of it) and very close friend of Akira, as well as long-time acquaintance of Ryouhei's. Has a somewhat serious and responsible outlook of things, which, along with being somewhat gullible, makes her a frequent target of Ryouhei's and Akira's friendly antics, often prompting retribution towards the later. Her tsun side is mostly reserved for Ryouhei though, as Haruka generally doesn't do anything to provoke her. (And she is of the tsundere type that softens over time, not keep flopping between tsun and dere).
Motoka - Maid working at Kazuha's house, she is occasionally there to collect Kazuha after school via car, if the later is pressed for time for whatever reason. Talks in a rather playful/laid back manner, and is fond of beer. A rather inconsequential appearance during normal course of things, and i doubt we will be seeing much of her.
Ryouhei - the usual "best buddy" character who is quick to befriend Haruka when the latter transfers in to his class, thus bringing Haruka in to this little circle of friends. Horrible at studies but quirky in personality, he tends to act like some lady killer (Though all the ladies, save for Akira, seem to hate him for this
) and a general jokster, often having the assistance of Akira in his antics on a moment's notice. Childhood friend of Akira, and a long time acquaintance of Kazuha, much to the latter's dismay.
