Долгожительство — демоны живут практически вечно. Срок в десять тысяч лет для них ничтожен, но они всё же стареют; (Longevity - demons live almost forever. Ten thousand years isn't a long time for them, but they do get older;) (https://highschooldxd.fandom.com/ru/wiki/%D0%94%D0%B5%D0%BC%D0%BE%D0%BD%D1%8B) In any case, it is most likely a translation problem. So let's just agree that demons can live obviously more than ten thousand years in this fanfic (there is even a logical explanation). Although I must praise you for your persistence.

”Hyoudou Issei! I can lose to you dozens, no, hundreds of times! However, remember! The life of demons is practically eternal! And one day I will overcome you! I don't even need ten thousand years! Within a few years I will burn you with the Phoenix hellfire and turn you to ash!” High School D&D DX.1. Chapter “Life.DX Phoenix of the Battle School Building DX?”. Riser says that ”the life of demons is practicallt eternal”. I couldn't find proof in English, so here's in Russian. Just check with a translator.
