Her personality exhibits remarkable patience and approachability. Mokuren struggles to refuse requests for help, leading others to frequently rely on her, stemming from her belief that aiding others fulfills the medical team's purpose. Her close friend Tsubaki characterizes her as fundamentally calm and trustworthy, not incapable of setting boundaries. Mokuren rarely displays anger, maintaining composure even under deliberate provocation, such as remaining unperturbed when Housenka and Sazanka drew on her face during a contest. Her frustration surfaces minimally only when conflicts escalate to physical altercations among villagers.

Mokuren interacts regularly with teammates Housenka and Tsuwabuki. Her friendship with Tsubaki involves mutual respect and observation. An episode involved a village-wide search for specific herbs she identified as necessary for medicine during an illness.
