Profile

A hacker of Veritas, Millennium Science School's infamous hacking group.

Wiretapping is her specialty, and she takes great pleasure in eavesdropping on other people's private conversations. A socially awkward young lady who addresses even younger students with formal deference. In real life, she's mousy and shy, but on the internet she's a surprisingly glib wordsmith.

Kotama's full name is Otose Kotama. Kotama's birthday is January 5th, and Kotama stands 5'2" tall. Kotama is voiced by 高川みな in Japanese and Lee Eunjo in Korean. Kotama's hobby is wireless communications and wiretapping. mona drew Kotama.
