One person, two names
Isekai is Japanese for another world. In a reincarnation story, the hero keeps a memory of a modern name and wakes up with a noble one. The card shows the new name as title, first name and house. Your old name sits under it, written family name first, with its native script and meaning.
The role choice comes from a list of story roles: Villainess, Saintess, Duke's Daughter and more. Extra means a background character with no importance in the original plot.
The meaning echo
When both names share an idea, the pair can link them. Mizuki (美月) means beautiful moon, and Selina means moon. Hikaru (光) means light, and Helena means torch or shining light. A Korean pair works the same way: Bit (빛) is light or glow.
Not every pair has an echo, because it appears only when the meanings really share a word. Do not force one.
Check the old name too
English readers may see odd words in East Asian names. The Check meaning tag can appear on the before card. Sena (瀬那), for example, sounds like senna, a herbal laxative. Several Korean names that include Dong carry a similar warning for English slang.
