Itaru Shiodome is a supporting character from the anime A Lull in the Sea, primarily recognized as the father of Miuna Shiodome. He is a man of average height with short, black hair, and his appearance reflects his grounded and hardworking nature. At the start of the story, he is twenty-nine years old, and after a significant time skip, he is thirty-four.

His background is defined by personal loss and the responsibility of single parenthood. Having lost his wife, who was a childhood friend of Akari Sakishima, Itaru was left to raise his young daughter, Miuna, on his own while working as a fisherman for the Oshio Master Fishermen’s Cooperative. This situation led to a close relationship with Akari, who often helped care for Miuna, ultimately blossoming into a romantic connection.

In terms of personality, Itaru is depicted as a gentle and kind-hearted individual, though he can come across as somewhat unassuming or simple. His decision-making process in his personal life is marked by hesitation, which stems not from a lack of feeling but from a deep awareness of the complications his choices create. When Hikari Sakishima, Akari’s younger brother, confronts him about his intentions regarding a future with Akari, Itaru’s uncertainty leads to a physical altercation, reflecting the genuine but conflicted nature of a man trying to do the right thing in a difficult situation.

His primary motivation is the well-being and stability of his family. He works diligently, and after the birth of his son, Akira, he sacrifices to purchase a house, taking on financial burdens to provide a secure home for his new, larger family. This dedication solidifies his role as a quiet, dependable pillar of the Shiodome household.

Key relationships define his arc. His relationship with his daughter Miuna is central, and her initial struggle to accept Akari stems from a fear of replacing her deceased mother. His romance with Akari Sakishima is the most pivotal relationship in the story, one that challenges the social boundaries between land and sea dwellers. Through his marriage to Akari, he becomes the stepbrother-in-law to Hikari Sakishima, a relationship that begins with conflict but matures into a familial bond.

Itaru undergoes notable development from a widowed single father to a remarried husband and father of two. He navigates the social friction of an interspecies relationship, eventually finding acceptance and building a new life. His personal growth is less about dramatic change and more about the quiet strength required to face societal prejudice and the emotional complexities of blending a family.

While he possesses no supernatural or extraordinary abilities, Itaru is a skilled fisherman, proficient in his trade to support his family. His most notable trait is his steadfast resilience and capacity for hard work, which serve as his primary contributions to the story and his family’s happiness.
