Stenluke

Stenluke (シュティンルーク, shutinruuku) is Angelica’s sentient manablade. It speaks in a voice identical to Ferdinand’s.

Stenluke outwardly looks like a regular sword with a large feystone embedded into its pommel. It is the size of a dagger when sheathed, and grows to its full size when drawn.

Prior to Rozemyne pouring mana into it, the blade had a maximum length of 50 cm. It is likely that the length of the blade has continued to increase, but no exact measure has been given since.

Stenluke has a personality and voice similar to Ferdinand’s. It is formal, intelligent and disciplined. While it is strict with Angelica, it is very respectful to Rozemyne, calling her “master of my master.” Generally, it does not talk to anyone other than Angelica or Rozemyne.

Stenluke was initially a regular manablade. To compensate for the elemental affinities she lacked, Angelica fed it feystones and materials of different attributes. She also gave it mana whenever she could to grow the blade.

As a reward for studying hard and successfully passing her courses at the Royal Academy, Rozemyne promises to donate mana to Angelica's manablade. Her mana is only expected to grow the blade and potentially instill it with some of her elemental affinities.

While pouring mana into the blade, Rozemyne reflects that what Angelica really needs is more brainpower and more motivation to study, and she remembers her own experience with Ferdinand’s strict teaching style. As a result of her wandering imagination, Rozemyne accidentally makes the blade sentient and gives it Ferdinand’s voice.

Stenluke becomes a useful tool for Angelica, since it can remember important information for her, scold her when she slacks off on her studying, and caution her when she acts recklessly. However, it can only listen and talk while Angelica is holding it, meaning that she can’t entrust the blade to someone else so they can teach it in her place.

When Angelica begins to rely too heavily on Stenluke to remember information for her, Rozemyne forbids her from using it in classes at the Royal Academy. Stenluke agrees with the decision and abstains from providing help. However, thanks to Cornelius’s dedicated tutoring, Angelica just barely manages to graduate on her own.
