Constraint 4: No markdown, no asterisks, no headings, no bullet points (except within the array for the primer, though the prompt says "array of exactly 4 concise bullet points" but also "no bullet points" in the general instruction. Looking at the instruction "Write original, neutral, encyclopedic prose in plain text — no markdown, no asterisks, no headings, no bullet points", this usually applies to the prose style. However, the JSON key primer is an array. I will provide an array of strings. The "no bullet points" instruction likely refers to the text content within the JSON strings or the overall formatting of the output. I will provide a JSON object with an array of 4 strings).
Constraint 5: overview must be 160-220 words.
Constraint 6: primer must be an array of exactly 4 concise points.

Overview Draft:
In this season, Nozomu Itoshiki, also known as Zetsubou-sensei, continues his efforts to teach class 2-F about the inherent despair and darkness found in all aspects of life. As the world's most negative person, Itoshiki views words, culture, and life through a pessimistic lens. His mission to instill a sense of hopelessness proves difficult because his students are far from ordinary. The class includes a girl who is the most positive individual he has ever encountered, as well as his own personal stalker. Additionally, the student body features a foreign exchange student who possesses split personalities. The class is also managed by a perfectionist acting class president, a role necessitated by the fact that the actual class president cannot be seen by anyone. Through these interactions, the series explores the comedic and animated struggles of a teacher attempting to spread negativity among a group of highly unconventional students. (Word
