Episode 1 Summary
Trinity

Keita Ibuki's mother passed away in a road traffic accident not too long ago and now he is living alone although his childhood friend Akane Sano does help him out. His mother's death still troubles him to this day and one evening while on the way home, he comes across someone that looked exactly like her standing on a platform.

The next day at school, his classmate Risa Yamada tells him how she and her friend came across someone that looked exactly like her too at the concert yesterday. Ibuki puts on a serious tone and warns her to be careful of an accident. Risa laughs it off, amazed that Ibuki believed in the recent rumours about "Doppelgänger".

That evening, Ibuki is on the way home alone again. While eating at the regular ramen stall, he meets a hungry odd looking girl while talking about doppelgänger. It was a term referring to how there are two others that resemble oneself. If one was to see one of them then, it means one may soon meet their death. That was what happened to his mother and that was why he believes in it. However, the girl corrects him claiming that doppelgänger was just a made up story. What really existed was the Doppel Liner System" which is to keep the life energy on earth "Tera" in balance. Each person is divided into two others - the strongest is known as the "Root" and the weaker two are known as the "Subs". The Subs are terminated for some reason or the other such as an illness or accident then their Tera energy absorbed by the Root.

Before the girl could finish the ramen Ibuki offered her, a largely built man approaches her and smashes his baseball bat mercilessly into the side of her head, catapulting her off the seat and onto the ground. Both the stall owner and Ibuki try to help her but he was too strong. Eventually the girl picks herself up and angry that the man wasted her bowl of ramen away, she fights and a fury of attacks are exchanged. After winning the battle, the girl apologises for getting them involved and introduces herself as "Kuro" a "Mototsumitama". Before Ibuki could ask her what that meant, Kuro rushes off leaving only the words that she is off to kill her older brother.

Returning home, Akane was preparing dinner even though Ibuki didn't want her to care for him but she insists. She had noticed that he's been keeping his distance from people since the death of his mother and friends because he feels it was him that brought misfortune to anyone he was with. As if on cue, a news report tells of his classmate Risa's death.

The following day, flowers were placed on Risa's desk. Ibuki rushes out of the classroom, running off to somewhere isolated to cry out in sadness but things weren't going to end there. As he made his way home, he meets his next door neighbour Mayu smiling at him. She tells him how she saw someone that looked just like her earlier during the day before walking out onto the road just as the green man on the light appears. Ibuki tries to stop her but a truck comes crashing into her dragging a bloody trail across the road. Kuro appears beside Ibuki speaking in a calm voice that she wasn't a Root as he stared on in shock.

Thoughts

Ah, a story with something just a little bit different. My interest is a little more piqued for Kurokami. This is probably the longest summary I've wrote so far for this season's shows and now I know a bit about "Doppelgänger" too. The fight scene was animated very smoothly and there was quite an impact when Mayu got run into. They built up enough of her innocent character to make the viewer feel sad for the sudden death I think.
