This essay discusses the becomings of the character Saya in the visual novel Saya no Uta (2003), developed by Nitroplus. Being perceived as either girl or monster, Saya is trapped between these notions, within the endless becomings of her conceptualisation. Using the idea of becomings developed by Gilles Deleuze in Logic of Sense (1969) this essay aims to understand how Saya could be perceived through her becomings. Compared to the character of Alice from Alice in Wonderland, which is a prevalent subject through Logic of Sense, Saya shows many similarities with Deleuze's unofficial heroine. Donna Haraway's A Cyborg Manifesto (1985) is used to understand the underlying machinic desires of Saya, and how she becomes a productive force through consumption of the notions that try to define her. The dichotomy of girl and monster is further explained using Rosi Bradiotti's Nomadic subjects (1994), where the monster not only becomes a manifestation of the grotesque, but also a subject of the monstrosity within its discursive concept. The ambivalence of the monster is the duality between the abhorrent and the adored. The analysis shows that Saya, whether she is released to the world or not, renders the dichotomy useless in relation to the force of the materiality that somehow persists through, whatever its meaning, and what it ultimately is subjected to.
