Inuyasha's father, who will henceforth be referred to as Inutaishou, despite remaining yet unnamed, and Sesshoumaru are standing on a snow-covered beach, speaking with one another. Inutaishou is bleeding with has his back to Sesshoumaru. I'm pretty sure Sesshoumaru was not the one who made his father bleed, but he does seem to be criticizing his father's choice to storm a castle. Inutaishou, by the way holds all three swords at this point: Tessaiga, Tenseiga, and Souunga. His father says something about protecting those you love, transforms into his real form, and runs into the woods towards the castle. Sesshoumaru does not follow.
Setsunano Takemaru is a samurai at the castle towards where Inutaishou is headed. There are multitudes of Samurai, guards and priests there awaiting Inutaishou's attack. Within the castle is held Izayoi, who seems to have just given birth to little Inuyasha. Takemaru goes into the room and talks to her, then kills her.
At this point, out of the forest comes running Inutaishou in his human form unleashing one Kaze-no-Kizu after another busting down walls and killing most everyone there. He rushes into the compound and he is met by Takemaru. Takemaru pulls out his sword and they rush at one another. Inutaishou takes off Takemaru's arm and rushes into the castle. I forget how the castle caught fire, but it did. Inutaishou comes into the burning room and finds Izayoi dead and the crying Inuyasha in her arms. He pulls out Tenseiga and resurrects her. Takemaru then comes in and Inutaishou pulls out Souunga; they fight while Izayoi gets away. He tells Izayoi to run with Inuyasha. She says "Inuyasha? . . ." and his last words to her are "Sono ko no na wa Inuyasha! (That child's name is Inuyasha!)" She then runs away. She gets out in time for the burning building to collapse upon Inutaishou and Takemaru. I'm guessing that this is how Inutaishou dies.
