The Tiny Witch from the Deep Woods: Volume 2

After a surprisingly long journey, Misha arrives in the Kingdom of Redford. Her identity as one of the People of the Forest grants her an exceptionally warm welcome, though her first taste of high society ends up being a bit bewildering for her. However, it’s not long before she’s back in her element. After a few days of living in Redford Castle, she encounters the king’s younger sister, a frail and sickly girl just about Misha’s age. Driven by her insatiable curiosity, she can’t help but investigate what is causing the princess’s illness, even when it leads her to butt heads with Redford’s nobility.
