Kirat Rai
Indic

The Kirat Rai script is an abugida used for writing Bantawa, an eastern Kiranti language of the Sino-Tibetan family. Bantawa is spoken in Sikkim and Nepal by almost 400,000 people. The script appears to be a modification of Khambu Rai, which is used for writing the same language.
Kirat Rai is written with thirty-one consonant letters each containing an inherent /a/ vowel, seven vowel diacritics for changing the inherent vowel, a virama for cancelling the inherent vowel, and a vowel carrier which can be used in combination with the vowel diacritics for writing word-initial vowels.
