Volume 4 has offers two poignant ikigami stories. In the first, we meet a young man that was inspired by a teacher as a child and has become a teacher himself in the hopes that he can make the same difference in other students' lives. He is betrayed by the student he most wants to help and, after receiving his ikigami, has a mental break and goes after the student's mother - who he blames for not providing enough love and support to his student. But there is still a chance for him to make a lasting impression on the student who needed his understanding the most....
And in the second story, we have an interesting story of a woman who got pregnant at a very young age. Most citizens wait until they've cleared the 24-year threshold so they won't risk leaving a child behind if they are destined to die. However, this young woman chose to keep her child and marry the father. Her life has been a struggle and her marriage is failing, but she lives for the joy her daughter brings to her. When she receives her ikigami, she doesn't trust that her childish husband will give her daughter the love and care she needs, so she makes a desperate attempt to change the course of her child's life in her final hours...while her husband, learning of the ikigami, struggles to prove to his wife that he can be a better man for the daughter he also loves...
