Tomoe Ohta (太田ともえ Ōta Tomoe?) is a minor character featured in Forbidden Siren 2. The daughter of Tsuneo Ohta and a resident of Yamijima Island, she is involved with a mob of fishermen chasing Kanae and Shu, acting as a second leader of sorts, with her father commanding them. However, she is among the population of the island who disappear after a red tsunami engulfs the land.
Born in Yamijima, Tomoe followed the traditions of the Ohta family; in the case of Kanae, never be tricked by figures who are allied with "the Ancient Ones", Mother and Otoshigo. Noting Kanae's weakness to sunlight, she saw that the young woman was an avatar working for Mother.
One night, Tsuneo and Tomoe held a meeting with the island's fishermen. Going along with their traditional beliefs, they decided to go after Kanae and see to it that she is captured for trying to set Mother free. With the plan set forth, Tomoe is absent at the fishermen's raiding of the Mikami household to catch Kanae murdering Ryuhei Mikami. However, she finds and attacks Kanae, who is with the young Shu Mikami. The fishermen surround them, but the ground collapses, sending the two into the water. Tsuneo says that "it's over", before the sound of a wailing siren (Mother's scream) is heard, and a red tidal wave covers the island, sending everyone on it to a false reality resembling it.
After the red tidal wave, Tomoe became dazed, and eventually runs into Mamoru Itsuki and Yuri Kishida, mistaking Yuri for Kanae before the two manage to run away from her. Hours later, she is faces a group of shiryo, spirits that work for Otoshigo. Running away from them, she falls off a height, landing only to be impaled by an antenae, dying a painful death.
Eventually, she is resurrected as a shibito when a shiryo possesses her. In this undead state, she goes to the Bright Win ferry, a ship from 1986 that disappeared and came to the island thanks to the fold in time caused by the tsunami. Making her way to the ferry, Shibito Tomoe runs into Yorito Nagai, a private in the Self-Defense Japanese military. In order to make his way around the ferry, Yorito defeats the vain shibito.
Moments before the seven seals containing Mother can be broken, she goes the Amusement Park, again encountering Mamoru and Yuri, who are in the process of breaking said seals. Likewise, she is incapacitated. Luckily for her, she leaves the area before the Yamirei, Mother's spawn, can attack her fellow shibito.
At some point, possibly during the battle between the shibito and yamirei, her body is taken over by the yamirei, transforming her into a Yamibito. She returns to the Bright Win ferry, and by the time Mamoru arrives to it with the intention of wiping out all yamirei and yamibito he can find, her yamimrei-possessed body has completed its evolution, turning her into a Dog Yamibito (otsu-yamibito). In this state, she wanders in the engine room, talking to herself about what it could be like to visit the mainland, and missing her hair comb that her father bought for her as a present. Mamoru, following his mission as part of his own form of redemption, defeats Dog Yamibito Tomoe, rendering her unconcious.
Her final appearance is at Spider's Thread, making a home for herself. Mamoru once again confronts her, this time with Ikuko Kifune by his side. Mamoru wields Tomoe's Mekkoju branch, reserved for her at birth. Upon her defeat once again, the branch envelopes her body, turning it into a tree, thus ensuring that her spirit goes to Heaven in piece, like with her father shortly before her.
Tomoe's personality can mainly be summed up as vain; she tends to complain about losing her hair comb and wishes to recover it. This can be evidenced by her talk of wanting to find it again when she is a Dog Yamibito. However, she is also very loyal towards her father, which means that she is willing to protect him and agrees with him.
Her loyality to following the rules laid out by her ancestors in the Ohta family result in her being very aggressive towards Kanae and later Yuri, due to correctly believing them to be agents of the "Ancient Beings".
