DRAGON Arc

 * Main article:DRAGON Arc

Tochtli first appeared in volume 19 when GROUP was riding Shiokishi's base. She is seen along Tecpatl; however she "wasn't conscious" since Tecpatl saw the need of sedating her to the point where she was unable to talk in order to freely use her bones as materials for the attacks of his Grimoire without objection.

After seeing the situation, Etzali decides to face Tecpatl and once he defeats him, he decides to use his grimoire to restore health to Tochtli, thinking on Xochitl's bests interests.

Homecoming Arc
Tochtli is seen recovering, interned in the same hospital and staying in the same room as Xochitl, there she jokingly points out how Etzali's presence is of great help to them and seems to read quite easily Xochitl mood swings and her feelings towards Etzali, hence she easily uses such quality to "add fuel to the fire" of their arguments. Tochtli also calls Etzali "onii-chan", however it seems that she does this only to get in Xochitl's wrong side rather than affection towards Etzali.

Magic God Othinus Arc
In the final recreation of the world by Othinus created specifically to break Touma's spirit, known as the Version_Omega world in-text, where several characters from the original world have been "saved" or have not experienced great tragedy, people from the magic side like nuns are allowed to enter Academy City, and seemingly have no complex against science. Etzali, Xochitl, and Tochtli are first seen by Kamijou Touma during his "last meal" as he decides on what method he should have himself killed. Here, Xochitl asks Etzali what they should do now, but he replies that she should ask Tochtli as she was the one who heard the commotion. Tochtli then complains on how Etzali is forcing it on her as she says that Xochitl is practically his little sister. It is unknown what commotion Etzali is referring to, but is likely the festival that is happening at that time.

Her first appearance is when she uses a Mixcoatl to retrieve the stranded Xochitl from Liberal Arts City. She notes on how Saten Ruiko is kind and seemed genuinely worried over Xochitl. Later, when the fight against Liberal Arts City climaxes she chooses to support Xochitl stance of leaving civilians evacuate, rejecting their direct orders; even though this meant fighting off people from her own Magic Cabal who were following orders obediently.
