Similar Difficulty Page

The "Similar Difficulty" page shows series with difficulty levels close to the one you're viewing, including slightly easier and slightly harder series.

• Results are sorted randomly, with up to 12 per category.
• Reloading the page may show different results.
• Series you've marked with a reading status only appear in the "You've Read" category.

Similarity Criteria

Series are categorized based on a mix of series-specific and user-specific criteria. Each series appears in only one category at a time but may move to another upon reloading. These criteria may be adjusted in the future, and furigana is not currently factored in.
