Spoiler for Minagoroshi-hen + Matsuribayashi-hen:

The story takes place in a junior high school, Tanashi Miyoko is in 3rd year. Considering the actions she took in the novel, and from Kai's TIPS # 38,48,49, it's very likely that she is Takano Miyo. Takano Miyo is indeed the name that Tanashi Miyoko changed to, to show that she's the sucessor of Takano Hifumi.

Spoiler for Novel spoilers:

However, despite all that, certain things don't check. Tanashi Miyoko does have a grandfather, but the key person "Takano Hifumi" was never mentioned once in the whole novel. Also it doesn't make sense why she is in Shishibonoshi at that time. Also, it's not known what her future plans are (after graduation). From Minagoroshi, the normal Tanashi Miyoko would most likely just move on to University without getting a medical licence. However, without that, it would be impossible to land her position and job in both the SDF and the Irie Institite.
