Enh

 Enh  was a Buddhist Arab who replaced Khoshy.

Appearance
She looks like nothing at all.

Background
When Enh was born, what she was named after followed the Arabic culture of naming a person after the first thing the mother notices after childbirth. When Enh was born, the father sneezed and coughed at the same time, resulting the sound of Enh, being the first thing the mom noticed.

Enh was taught the buddhist religions and wanted to achieve nirvana, and to not make any mistakes, she thought of everything as nothing and did absolutely nothing. She replaced Khoshy in ISC and the only thing she did was make the students look to the front without doing anything, even their exams.
