Girl from the Flash back
+ Show Spoiler +

Girl from You's memories, the Orihime of the story. Tries her best to play an older sister role, Promised him to marry him and make him listen to everything she says when they are reunited.

The game starts with the protagonist's memories of his first affection as he returned to a city he once lived it. He liked her, but as You monologued, it was not love. It was with a girl slightly older than he was. In a special place, the Look out over Hubarigasaki, where the story takes place. Where they talked about the stars of the Summer Triangle. Altair, Vega and Deneb. Then we find out this was the day before the protagonist moving out of the city. As a farewell gift the girl gave him a kiss on the forehead.

As he finished the flashback he walked in front of a school with 2 girls talking with each other about their club the Tenkuru(Astronomy lover circle shortened to Sky-circle) and how they can't use roof for Tanabata. Of course You having nothing to do with the girls walk past them only to hear a comment how he might be lost because the look out he is heading to is a dead end. Of course he still goes to check it out. Only to see the Look out is now barricaded with fences. Cursing his fate and how his hope for a reunion with the girl of his memories has been shattered. He remembers how the girl told him that when they are reunited they'll get married and he'll listen to whatever she says.

You unwilling to give up goes around the fence through the vegetation only to find a young girl that must not be out of primary school yet who looks extraordinarily similar to the girl of his memories only a lot younger, holding a large lunar scythe next to her. She tells him she has been waiting for him and how she can finally fulfill her promise.

The girl tells You her name, "Mare" which isn't the same as the girl from his memories. But their images look so similar it disturbs him. Not only did she know his name, she knew how he used to refer himself with boku instead of ore as well. You refered to her dress and her scythe to a Grim Reaper, so Mare just went with it. Still doesn't know who or what she is, You asked more questions about her only to get the answer, She is here to fulfill her promise of reaping his nightmare. for she was a Grim Reaper that reaps Nightmares.

Next morning we meet You's sister Chinami, who seems nothing more than a genki/ klutsy girl who lacks the ability to cook. Also we learn from the text that their mother is now deceased. Their current guardian is Shino, their mother's younger sister who is a author.

You goes out to meet Mare again at the look out. Mare points out on how his most important memories are nightmares and how he is in pain. Also she comments how she doesn't like reaping nightmares while people are experiencing them.

Next day You goes to the look out once more to see Mare. He talks to her about Tanabata only to realize she thought the day of Tanabata was a different holiday, one that she celebrates with cake instead of wishing cards. You tries to pursue to case but Mare didn't say much more than bid him farewell and disappears.

Next day while going out shopping with Chinami they meet a waitress in a restaurant. The maid waitress Minahoshi Asuho, was also one of the two girls that he say in front the Academy on the first day. During his conversation he finds out that they went to the same primary school together.

While on his way back You sees Asuho arguing with another girl about using the roof for Tanabata. This girl introduced as Hisakaki Komomo, the Student Council President. He also meets the other girl from day 1, Hisakaki Kosame

On the same day while trying to visit the look out, You was stopped by a girl with long black hair. She interrogates him but You refuses to answer her, the girl leaves, and You continues his way up there.

(too lazy to find the screenshot, Bustshot mode to the rescue)

He meets Mare, where she tells him to close his eyes, When You opens his eyes only to find that a crying Mare who has slashed him with her scythe and reaps him of his nightmare. The result was You losing the memory of his love's name. He could no longer recall her name.
