Haruna worked at Bunpro for several years. Most famously, she voiced the original grammar sentences before Bunpro hired a professional voice actor.
She also had a long-running thread on the forum called Haruna’s diary, where she would write a short-ish entry about her day. There wouldn’t be any furigana, but you could see how native Japanese speakers would write about common topics.
She also had audio recordings of her reading her diary entry, so you could also practice listening.
She left Bunpro about a year or so ago for a different opportunity, but she’s back and her diary is getting updates again!
