Might possibly be Chigusa Hara (原千草) for anyone else wondering.
Edit:
Might actually be Sesera Harukawa (春川せせら) and the serial for the video is wrong. It should be AGEMIX-321. Chigusa's videos are still great though.
Buying resources out of their own pockets, spending energy and effort, with almost no return so that everyone can enjoy the cultural and entertainment products of developed countries at almost zero cost walking in the dark to serve the light, they are real heroes
