On VIP, ‘Ego-chan’ Joins the Sunday ‘Tenimyu Roleplay’ Thread — Regulars Swap Fan Art and Have a Blast

Background and Key Points

Anonymous message boards on 5channel (5ch, the successor to the original 2channel) are organized into hundreds of themed “itaraban” boards, and News VIP (ニュース速報VIP) is one of the site’s oldest and most trafficked, prized for a chaotic, in-joke-heavy culture built around total anonymity. Crucially, VIP does not display poster IDs by default, so regulars cannot verify who is who from post to post — a structural quirk that has spawned “narikiri” (roleplay) threads, where a poster adopts a persistent persona and returns week after week to interact with the same crowd, essentially running an ongoing character rather than a one-off post. “Tenimyu” is fan shorthand for the Prince of Tennis Musical, a stage adaptation of the tennis manga/anime “The Prince of Tennis” that launched in 2003 and became a flagship of Japan’s “2.5-dimensional” musical theater boom, casting young idol-adjacent actors as the show’s teenage tennis players; it has a large, mostly female fanbase, which is the joke underpinning a male-dominated board hosting a “Tenimyu roleplay” ritual.

The thread doesn’t really argue over facts so much as it splits in tone: most posters treat Ego-chan’s return as a nostalgic, low-stakes hangout (fan art, teasing about her look), while a few push it toward flirtation and declarations of romantic interest, which she deliberately downgrades to “fellow member” status.

What outsiders will likely miss is that none of Ego-chan’s personal details — age, measurements, prefecture, even gender — can be confirmed on an ID-less board; the persona’s consistency across weeks is itself the performance, not verified biography.
