Source Analysis:
[1] TMDB: Title is Cardfight!! Vanguard: Legion Mate (Japanese: カードファイト!! ヴァンガード レギオンメイト編, Hepburn: Kādofaito!! Vangādo Region Meito Hen, lit: Legion Mate Chapter). Aired March 9, 2014 to October 19, 2014. Total of 33 episodes.
[2] IMDB: Cast/crew info.
[3] Wikipedia: Redirect page.
[4] TMDB: Aichi Sendou is a timid third-year middle school student. He has a card called "Blaster Blade" given to him when he was little. Toshiki Kai is a cool-hearted high schooler who introduces Aichi.
[5] MyAnimeList: Card game is Cardfight Vanguard. Players are called "cardfighters".
Overview: I need 160-220 words.
Looking at the sources: The sources provide the title (Cardfight!! Vanguard: Legion Mate), the Japanese title, the airing dates (March 9, 2014 to October 19, 2014), the episode count (33), and some character info (Aichi Sendou, Toshiki Kai, Blaster Blade).
Problem: The sources do not provide a narrative arc for Season 4. They only provide the title and airing info for Season 4. The character info (Aichi/Kai/Blaster Blade) is general series info, not specific to the Season 4 narrative arc.
Constraint Check: "Write ONLY verifiable facts that are explicitly supported by the provided SYNOPSIS and SOURCES. ... If a detail is not in the provided material, you omit it rather than guess."
If I cannot write 160-220 words about the narrative arc because the sources don't contain the narrative arc for Season 4, I must state what is available or I will fail the word count constraint if I try to fluff it. However, the prompt says "produce a JSON object with keys... overview: factual 16
