Freminet is an renowned undersea diver for the Court of Fontaine in the Fontaine region, the realm of Water of Teyvat, the main setting of Genshin Impact. Freminet is usually a very reserved and introverted person, preferring to stay out of the spotlight and instead go diving in the ocean. Despite being good at diving, he has low self-esteem and believes himself to be bad at everything else, despite being very good with tinkering and clockworks, having his own mechanical penguin called Pers.
