Cyberfront is bringing two of Xuse’s PC games to PSP. Aselia the Eternal is coming a month late, March 8 instead of February 9. This version has been rebalanced and has additional cut-in images. (See a trailer here.)
On April 19 you can pick up the sequel Seinarukana: The Spirit of the Eternity Sword 2 for PSP. Cyberfront seems to have added more to this port since Seinarukana for PSP has 35 new illustrations, extra voice acting, and an improved scenario.
While neither game has been announced for PSP, JAST localized Aselia the Eternal for PC.
