Francois is Ryusui's faithful and extremely talented butler whose services were well sought out and coveted before the Petrification. They are demonstrated to be a supreme chef.


Francois is a person of average build and ambiguous gender. They have light hair with corkscrew curls.



They are extremely loyal to Ryusui, as shown by him being their first concern after being depetrified. They are always calm and composed, showing emotion very rarely. They seem to take great pride in her job, and would never compromise on quality.

Skills and Abilities

Master Chef

They are capable of making long-lasting rations and delicious food. On top of that, Francois knows how to procure high-quality food based on ingredients. If the ingredients are contaminated, Francois will not use it as seen as when Francois allows Suika to keep the pig as a pet once the pig was soaked with oil before.


Francois was able to travel from the former Tsukasa Empire to Ishigami Village with less rest. It is indicated that Francois' stamina seems suitable to do long-term walking rather than running.


  • Ryusui says he isn't sure what Francois' actual name, gender, or even nationality is, just that they are probably Japanese and named Francois.
    • However, most fans just treat Francois as a female due to their feminine appearance.
