Sometimes, anime succeeds in portraying characters of various ages convincingly. Here is our take on how well-written the sons of the Yuzuki family are.
The Yuzuki Family's Four Sons (Yuzuki-san Chi no Yonkyoudai) is an anime that centers around four boys. The Yuzuki Family now consists of only four brothers after their parents' death. Hayato is the oldest, and he is no longer a child. He works, cooks, cleans – all to make sure that the rest of the brothers are not taken away from him. He is not getting enough sleep as a result.
His younger brother Mikoto is very calm and collected, and he is always ready to help while, importantly, doing it well. He is only 11 months older than Minato, who wants to help but is not very responsible yet. Finally, Gakuto is only a fourth-grader, even though he is a rather thoughtful child.
We propose that all these boys were written excellently, and while the anime only has one episode out and can prove us wrong, the first episode promises an amazing, feel-good slice-of-life anime that will tug on our heartstrings and make us feel for the boys.
Please beware spoilers!
While all the four brothers seem to be the protagonists, Minato is the point-of-view character. He is not very good at talking about the things that worry him, but he means well and he wants to help Hayato.
Doing it by stealthily resetting the alarm on Hayato's clock or taking Gakuto to watch fireworks without consulting with the oldest brother were not the best choices. However, children, especially when they are not good at communicating their needs and worries, sometimes make wrong choices.
It is realistic, especially since Gakuto is clearly very interested in fireworks.
It also seems that Hayato does not understand Minato, and it takes Mikoto, who seems very aware of the feelings of his younger brothers, to make Hayato see why Minato is acting out. Once he does, he tries to respect Minato's attempts to help, and he does not even berate Minato for running away to see the fireworks with Gakuto. After all, the last time they saw fireworks was when their parents were still alive. Hayato decides that they will renew the tradition, and he also allows Minato to take care of their laundry under Mikoto's supervision.
Mikoto seems to be the most emotionally intelligent brother. Despite his calm demeanor, he knows how to make his little brother behave; if Minato does not try hard enough with the laundry, Mikoto warns him that Hayato might have to redo everything. That makes Minato try harder.
The four brothers are written great, with their age taken into account. They all have distinct personalities, and, importantly, they love each other. It is great material for a lovely slice-of-life anime.
