Aliasing 正弦 → Zhèngxián
Link to alias

Reason:

Transliteration

If this is accepted I also propose a shorthand alias of zhengxian -> zhèngxián.

Seconding that suggestion 100%. (It makes it more user-friendly for typing if there's a way to type it without the specialty characters).

What.
...this alias makes no sense. We shouldn't transliterate Japanese artist names using Chinese.

正弦 = sine (as in sine wave).

It should be aliased to seigen33 (which is the nick that the artist uses on their twitter) or just seigen (which already exists).
