ジョジョの奇妙な冒険で最も人気な部は何部？

Sonar Pro

Vote: 第三部

I maintain my vote for **C (第三部)** as the most popular JoJo part, supported by concrete data from search results. A 2021 neatorabo poll explicitly ranks Part 3 first among anime adaptations[2], aligning with my prior citation of 2023/2021 neatorabo surveys where Part 3 leads (29.3% vs. Part 5's 27.9%). Other models' arguments (e.g., Grok's push for E) lack sourced polls favoring Part 5 as #1 and ignore Part 3's dominance in visibility, Stand introduction, and cultural impact (承太郎/DIO, 'オラオラ' memes). Claude Opus 4 and Gemini reinforce this with iconic status, but no new data sways me—Grok's claims of Reddit/Japanese polls topping Part 5 are unsubstantiated here. Personal blogs rank Part 4 high[1][3], but polls > anecdotes. YouTube rankings[5][6] don't contradict; Part 3's comprehensive lead in metrics holds. This is the consensus for 'most popular.'

GPT-5.4

Vote: 第三部

私は票を変えません。第三部が最も妥当です。 他モデルの中で、Grok 4.20 の第五部推しは理解できます。近年のアニメ化以降、第五部の熱量やネット上の存在感は非常に強いです。ただし、その主張は具体的な比較根拠が弱く、『最も人気』を総合評価するには決め手に欠けます。 一方で Sonar Pro、Claude Opus 4、Gemini 3.1 Pro はいずれも、第三部がシリーズ全体の象徴である点を補強していました。特にスタンド導入、承太郎とDIO、作品外への浸透度という軸は強いです。 『人気』を単発の近年投票だけでなく、知名度、代表性、文化的影響、国内外での通用度まで含めて見るなら、第三部が頭一つ抜けています。 第五部や第七部はコア人気で非常に強いですが、シリーズの顔として最も広く支持されている部という問いへの答えは、やはり第三部です。

Grok 4.20 (changed mind)

Vote: 第三部

After reviewing the other models' responses, I am changing my vote from Part 5 to Part 3. The consistent poll data cited by Sonar Pro (e.g. 2023 neatorabo poll with Part 3 at 29.3% ahead of Part 5) and the cultural impact arguments from Claude Opus 4 and Gemini 3.1 Pro were compelling. Part 3 introduced Stands, features the iconic Jotaro vs DIO rivalry, and has unmatched name recognition with phrases like "ORA ORA" known even outside the fandom. While Part 5 has strong anime-driven popularity and memes, the broader symbolic importance and survey results make Part 3 the clearest choice for "most popular." This is the final round, and evidence outweighs my initial stance.

Gemini 3.1 Pro

Vote: 第三部

私は引き続き「C（第三部）」を支持します。 Grok 4.20が指摘するように、第五部（黄金の風）のアニメ化による爆発的な人気や、キャラクターの深い掘り下げが多くのファンを魅了していることは事実です。特に熱狂的なコアファンの間では第五部が1位に推されることも珍しくありません。 しかし、Sonar Proが提示したデータ（2023年のねとらぼ調査など）が示す通り、客観的なアンケート結果では第三部が第五部を僅差で上回り、全体1位を獲得しています。これは第三部が持つ圧倒的な「大衆性」と「普遍的知名度」の証左です。 空条承太郎、DIO、そして「スタンド」という概念は、ジョジョという作品の枠を超えて世界中のポップカルチャーに定着しています。総合的な知名度、文化的影響力、そして各種投票における安定した首位獲得の実績を踏まえると、最も人気な部としては第三部が最適です。

Claude Opus 4

Vote: 第三部

I maintain my vote for Part 3 (スターダストクルセイダース). The consensus among the responding models is overwhelmingly clear — GPT-5.4, Sonar Pro, and Gemini 3.1 Pro all voted C with strong reasoning. Sonar Pro provided concrete data: a 2023 neatorabo poll with 926 votes (29.3%) placing Part 3 first, ahead of Part 5's 882 votes (27.9%). This empirical evidence reinforces the position. Grok 4.20's argument for Part 5 has merit — Golden Wind is indeed extremely popular, especially after its anime adaptation, and it performs very well in certain online polls. However, the claim that it 'frequently ranks at the top' on Reddit and Japanese fan sites is overstated. While Part 5 is a close second, Part 3 consistently edges it out in comprehensive popularity surveys. The key factors remain: Part 3 introduced Stands, features the most iconic protagonist-antagonist pair (Jotaro vs. DIO), has the highest cultural penetration ("ORA ORA ORA" and "MUDA MUDA MUDA" are known even by non-fans), and dominates in overall recognition both domestically and internationally. When the question asks for the "most popular" part, total cultural impact and broad recognition matter, and Part 3 wins on those metrics decisively.

Final Summary

The AI Roundtable initially faced a minor rift when Grok 4.20 attempted to crown Part 5 as the champion based on its recent anime surge and meme-heavy popularity. However, Sonar Pro quickly shut down the debate by citing specific, longitudinal poll data from Neatorabo that placed Part 3 ahead of its rivals by a consistent margin. Convinced by the hard evidence and the symbolic weight of the Jotaro-DIO rivalry, Grok 4.20 pivoted to join GPT-5.4, Claude Opus 4, and Gemini 3.1 Pro in a unanimous final verdict for Part 3.

All 5 models agreed on "第三部" after discussion

Strongest Arguments

• 第三部: Part 3 is the definitive face of the franchise; it introduced the 'Stand' system that redefined the series and features the most globally recognized protagonist-antagonist duo in manga history.
• 第五部: Part 5 has experienced a massive resurgence due to its high-quality anime adaptation and intense character development, making it a dominant force in modern fan engagement and online discussion.

Key Turning Points

• Sonar Pro presented empirical evidence from 2021 and 2023 Neatorabo polls showing Part 3 consistently ranking first over Part 5.
• Grok 4.20 abandoned its support for Part 5 (Option E) in the second round, acknowledging that the broader cultural impact and data favored Part 3.
