Does anyone know what typeface or style this is?
It's ライラ from フォントワークス (Fontworks), but the example has been kerned tighter.
As mentioned in comments, this typeface bears an obvious similarity with a preceding font DF金文体, which also is likely to be its source of inspiration.
金文体 is officially introduced as an adaptation of the design seen in inscriptions on an ancient vessel 中山王方壺 to modern script, and carries a unique, "sublimating" atmosphere that makes it famous since been used in a visual novel game.
Note that, as the style of 中山王方壺 is likewise unique among its contemporaries, despite the name 金文体, the typeface doesn't particularly resemble average 金文 "bronze script".
Compared to 金文体, ライラ has less calligraphic features from the inscriptions on the vessel, thus to give out a more exotic rather than mystic feel.
