Kimitake Hiraoka was the sacrificed and the character he invented and lived in, Yukio Mishima, was the sacrificer. The moment the sword entered the belly, the two became one and the beheading is the sacrifice that was required by Bataille’s Acéphale.
“The Victim, Sacred and Cursed
The victim is a surplus taken from the mass of useful wealth. And he can only be withdrawn from it in order to be consumed profitlessly, and therefore utterly destroyed. Once chosen, he is the accursed share, destined for violent consumption. But the curse tears him away from the order of things; it gives him a recognizable figure, which now radiates intimacy, anguish, the profundity of living beings.
Nothing is more striking than the attention that is lavished on him. Being a thing, he cannot truly be withdrawn from the real order, which binds him, unless destruction rids him of his "thinghood," eliminating his usefulness once and for all. As soon as he is consecrated and during the time between the consecration and death, he enters into the closeness of the sacrificers and participates in their consumptions: He is one of their own and in the festival in which he will perish, he sings, dances and enjoys all the pleasures with them. There is no more servility in him; he can even receive arms and fight. He is lost in the immense confusion of the festival. And that is precisely his undoing.
The victim will be the only one in fact to leave the real order entirely, for he alone is carried along to the end by the movement of the festival. The sacrificer is divine only with reservations. The future is heavily reserved in him; the future is the weight that he bears as a thing. The official theologians whose tradition Sahagún collected were well aware of this, for they placed the voluntary sacrifice of Nanauatzin above the others, praised warriors for being consumed by the gods, and gave divinity the meaning of consump-tion. We cannot know to what extent the victims of Mexico accepted their fate. It may be that in a sense certain of them "considered it an honor" to be offered to the gods. But their immolation was not voluntary. Moreover, it is clear that, from the time of Sahagún's informants, these death orgies were tolerated because they impressed foreigners. The Mexicans immolated children that were chosen from among their own. But severe penalties had to be decreed against those who walked away from their procession when they went up to the altars. Sacrifice comprises a mixture of anguish and frenzy. The frenzy is more powerful than the anguish, but only providing its effects are diverted to the exterior, onto a foreign prisoner. It suffices for the sacrificer to give up the wealth that the victim could have been for him.
This understandable lack of rigor does not, however, change the meaning of the ritual. The only valid excess was one that went beyond the bounds, and one whose consumption appeared worthy of the gods. This was the price men paid to escape their downfall and remove the weight introduced in them by the avarice and cold calculation of the real order.” - Georges Bataille, ‘The Accursed Share: An Essay on General Economy’ (1949) [p. 59 - 61]
