Fumetsu no Anata E /不滅のあなたへ/给不灭的你
It, a mysterious immortal being, is sent to the Earth with no emotions nor identity. However, It is able to take the shape of those around that have a strong impetus.
At first, It is a sphere. Then, It imitates the form of a rock. As the temperature drops and snow falls atop the moss, It inherits the moss. When an injured, lone wolf comes limping by and lays down to die, It takes on the form of the animal. Finally, It gains consciousness and begins to traverse the empty tundra until It meets a boy.
The boy lives alone in a ghost town, which the adults abandoned long ago in search of the paradise said to exist far beyond the endless sea of white tundra. However, their efforts were for naught, and now the boy is in a critical state.
Acquiring the form of the boy, It sets off on a never-ending journey, in search of new experiences, places, and people.
不死起初是一个被投放到人世间的“球”。
它具有“幻化为刺激源形态的能力”和“死后重生的能力”。
逐渐地，不死从相知相遇的人们那里学到了生存技能，
等待不死的是与宿敌•敲门人的壮烈战斗，与深爱之人的离别……
