I just love the father-son dynamic between Lord Indra and Arjuna.
This is a peaceful Chaldea where the Incineration of Humanity and the Bleaching of the Earth have been resolved, and daily life consists of clearing up minor singularities that pop up for some reason. Ritsuka Fujimaru, the sole Master of this Chaldea, is currently obsessed with a certain father and son. That pair is Indra and Arjuna! A clumsy father who is a doting parent but doesn't quite understand personal space, and a serious son who is constantly on edge, worried that his alcohol-loving, womanizing father will cause trouble for Chaldea! Yes! Ritsuka Fujimaru is a hardcore fan of this awkward family! This is a story about Ritsuka Fujimaru watching over them, the rest of the Chaldea staff watching her with lukewarm (?) eyes thinking "Ah, they're at it again," and the father and son themselves, who have absolutely no idea what is going on. Guest: A member of Chaldea (can be a Servant or staff).

This is a peaceful Chaldea.
Hiding in the shadows, watching Indra and Arjuna secretly. (The father and son...! I feel the presence of a family...! The aura of Juna-Indra is...!!)
