Raph-chan/Chronology

Volume 8
After being transported to Glass' world, Naofumi is separated with Raphtalia. He is then convinced by Ethnobalt to form a shikigami to help in the Naofumi. Naofumi then creates a Shikigami by mixing his own blood with Raphtalia's hair, resulting in Raph-chan's "birth." Raph-chan's creation process was actually quite unusual since she formed even though the ritual ran out of control for an unknown reason. Raph-chan also developed a sense of self immediately which is unusual for a shikigami. However, Raph-chan proved to be essential for finding Naofumi's missing party members.

Volume 12
During a discussing with Rat, Naofumi revealed that his goal is turn Raph-chan into a specified of her own. Rat then suggests increasing Raph-chan's mutability which he ends up doing.

Volume 13
The effects of raising Raph-chan's mutability finally seems to be reaping results as Raph-chan suddenly gains the ability to level-up. While in Siltvelt, Raph-chan also becomes essential in protecting Naofumi from women the Siltveltian leadership had set to ambush him.

Volume 15
Raph-chan had slowly evolved over time through shikigami power-up methods and fighting in Q'ten Lo. By this time, a majority of the monsters within Naofumi's village had levelled up enough to perform a class-up ritual. However, while at the dragon hourglass, Raph-chan had provided the monster the option to take a special raph-chan class-up option. This option changed their form into a copy of Raph-chan, gave them transformation abilities and greatly increased their stats. Against Raphtalia's wishes, all monsters who participated in a class-up ceremony selected the raph-chan class-up path. These monsters became the first of the "Raph" species where several sub-species existed. During these ceremonies, Raph-chan further mutated and gained the "C'mon Raph" skill.

Later on, after hearing the dragons and filolials fighting over making Naofumi's village their territory. Naofumi declares his village as Raph territory.

Volume 16
Raph-chan, leading others in the Raph species, conducted a mysterious ceremony upon the largest Sakura Lumina tree of Naofumi's Village. This resulted in Raph-chan II being reborn who Raph-chan promptly introduce to Naofumi. Raph-chan also gained the ability to use C'mon Raph herself to summon any of the Raph species.

During the defence against Takt, Raph-chan fought against Takt's illusion specialist Tulina with Raph-chan II. Together, they are able to defeat the fox woman.
