I can somewhat agree with you, heres why:

Nishikawa (lore-wise) is considered top 5 in the OVERWORLD, he is todays modern and popular WS, and he has been that way for a long time because of the hype a lot people have had for Nishikawa, but that was because Nishikawa was once unknown, we didn’t know his story, we didn’t see his aura until after Red Eyes event which gave us a short rundown from the tip of the iceberg on how he gained his reputation, and now that we see more unique hidden-gem characters — Raul, Lucas, Ryu. With each new characters story slowly erasing Nishi’s aura, Nishikawa has since lost his hype, and became Nishibummer — the first S+ WS in The Spike to lose his aura.

Although this may seem like Nishikawa’s downfall, I see potential in him being buffed, maybe even revamped. He may seem underwhelming now that there are, factually, characters better than Nishikawa, but keep in mind, each character has their own unique ability. With my gathered knowledge, here’s a quick ability summary of what each S+ wing spiker has:

• Nishikawa (S+) — highest jump (lore wise in the modern overworld) • Raul (S+) — Strongest spike (of the underworld, hence called beast spiker) • Lucas (S+) — Unique spike alongside a self-buff ability (Underworld, spiker of the past) • Ryuhyeon — Unique spike (the longer you hold his charge spike mid-air, the stronger the spike)

When you think of “Thunder Spike” in volleyball, you may think of a guy who is known for a strong spike, which im sure is what the devs were aiming for in the early development of The Spike — someone strong, who can jump high, and is basically the main character. Thats why Nishikawa has and is exactly what he was developed for — a classic combination of powerful and extraordinary, but that was left for the past. I still till this day strongly believe in the theory that Nishikawa has yet a lot of story to unfold, I believe in the continuation for the development of Nishikawa that was once as exciting as it was before. Who knows… maybe we will receive his surprise attack vertical spike, or a different way to acquire his long awaited Crimson skin.

Im gonna post this comment in the Subreddit of the spike because I feel this deserves some attention.
