Category:Characters by date of introduction

From The Heretic Knowledge Vault

Wherein are organized, at the request of the esteemed Viking-Sensei, the years when characters were introduced. Note that the organization may be by the year when we first hear the character's name, not the first time we see the character -- which may happen quite a bit later. In general, it's the first time we readers became aware of the character. There are a few exceptions (e.g. Bani Igaaru) when the existence of the character was known, but not his/her name; in these cases the first appearance is used.
