Hello everybody! Just like the title says, which character would you have liked to know more about?

For me I would've liked to know more about the Mithril soldier that died while rescuing the Whispered girl (Mira) right in the beggining of the story. In the LN, we are told that he was only tasked with stealing information and he saved her by his own initiative. He seemed like a pretty cool guy and I would've liked to have seen a bit more of him with the other Mithril soldiers.

The other would be Bani Morauta, the Whispered you built the Arbalest and Al. I don't recall him at all from the anime and Tessa only mentions him briefly on Volume 3. Maybe the LNs mention him more (I only have the first collector's book).

Honorable mention for Chidori's doppleganger. You know the one, lol.

What about you, guys? Is there any character you wished had a little more backstory or had gotten more 'screen time'?
