where in the novel is the anime currently at with the beginning after the end

The anime is not very far into the novel yet : based on the 24-episode plan and the anime’s current season focus, it appears to be around the early-to-mid school/academy arc , well before the later major novel events. The second season is being promoted around the Elderwood Arc , which places it in the earlier stretch of the story rather than deep into the novel’s later volumes.

Where that puts it

• Season 1 had 12 episodes, and the anime overall is planned for 24 episodes.

• The anime’s second season is explicitly tied to the Elderwood Arc in recent coverage.
• Since the novel is already finished while the comic is still releasing new chapters, the anime is still only covering an early portion of the full story.

Practical reading guide

If you want to continue from where the anime is headed, you should start from the early novel sections around Arthur’s academy-era storyline , rather than jumping to late-novel volumes. A safe approach is to begin a bit before the Elderwood material so you don’t miss setup and character introductions.

Quick note

There isn’t a single universally agreed chapter number in the sources I found for the exact anime-to-novel cutoff, so the best answer is that the anime is still in the early arcs and has a long way to go.
