The name in the tag is wrong, refer to http://social.gust.co.jp/pc/arnosurge/chara_04.html for spelling (イオナサル・ククルル・プリシェール) and http://arnosurge.eu/chara_04.html for the official romanisation (Ionasal kkll Preciel).
Aliases might also be needed (ionasal and ion_(ar_nosurge) together with ion_(ciel_nosurge) come to mind).
