Shojo Kaiju Anosillus the 2nd (アノシラス（２代目） Anoshirasu (2-daime)), simply known as Anosillus II, is a character in SSSS.Gridman. She is an independent kaiju and an acquaintance of Yuta Hibiki and Gridman as well as successor/progeny of Anosillus.
Anosillus is shown to have a mildly sadistic streak. She is somewhat socially awkward, and doesn't seem to know or care much about human social norms. Even so, she apparently a good person at heart, as she warned Yuta about the truth behind Kaiju attacks and a malevolent presence that manipulated Akane from behind the scenes. She says that she helped Yuta because her predecessor had a life debt with both Yuta and Gridman.
In spite of being awkward when it comes to human social norms, Anosillus possesses just enough social ability to blend into human community to avoid troubles as well as convincing Yuta that she's a trustworthy ally (though arguably not so much for Max). She also resourceful and intelligent, having collected a sum of coins for buying some food for both herself and others.
Anosillus's human/Repli-Compoid form has dark green hair tied into small pair of braids. She has slightly tanned skin and red eyes. Her outfit is comprised of a dark green double-layered hoodie with light green patches worn over a dress with pink, dark yellow, and light yellow colorations as well as red clef symbol on the chest, black shorts, and brown sandals. She also carries a large blue bag full of coins.
Other than human disguise and resourcefulness, Anosillus is able to enlarge herself as demonstrated in order to impress Yuta in their first meeting.
- Like the majority of characters in SSSS.Gridman, some elements of Anosillus's appearance are drawn from a Transformers series character. In her case, the color pattern of her t-shirts and hoodie mirrroring that of Wreck-Gar's body.
- Anosillus's statement that her predecessor owed Yuta and Gridman, coupled with "the 2nd" designation on her name in the Japanese credits, suggests that not only is SSSS.Gridman a sequel to Denkou Choujin Gridman, but also that she is in fact, the progeny of that series' kaiju Anosillus I who lives in the Computer World inside an electric piano. In Episode 6, Melody of Terror, the kaiju was taken control of by Takeshi Todo when he used a music composition to reprogram the kaiju's mind.
- Anosillus II wears the same shirt design as Unison, who is presumably a sound spirit, and companion of Anosillus I in Denkou Choujin Gridman Episode 6. As Gridman began to battle the mind-controlled Anosillus, Unison appeared and explained what's going on, and begged Gridman not to hurt Anosillus. Anosillus was freed by Yuka Inoue when she used an electric piano to play the song "Yume no Hero", the opening theme for that show, and transmitted it to Anosillus. In SSSS.Gridman Episode 6, Anosillus II used the piano version of the same song to awaken Yuta after he fell asleep during the train ride leaving the city.
