Sailor Moon Met Her Best Friend Back When She Was Just Usagi: Here Is Her Name
We're not talking about Mercury or Mars - Usagi's main friend even before saving the world.
Before Usagi Tsukino became Sailor Moon and met her magical team, she already had a real friend - Naru Osaka. She is considered Usagi's first and best friend in the original manga and the Sailor Moon series.
Naru is an ordinary schoolgirl, far from superpowers, but she is always there. She takes care of Usagi, supports her at school, shares secrets and laughs at her stupidity, not knowing that her friend saves the planet in the evenings. This is a sincere girlish friendship, not connected with a mission and destiny.
Yes, the Sailor Warriors appear later, but Naru remains a symbol of trust and normal life, which Usagi protects. And that is why she is Sailor Moon's best friend in the most human sense.
