Silent

In the anime, the hostage scene/suicide attack post detonation-failure is skipped in favor of developing Ryo's relationship with Katsume via projection. Thus, the kid's plan instead succeeds and his deeds are topical regardless of those whom died in the lab episodes ago.

Keith Silver has short skirmish with Keith Violet in manga; the anime partially keeps the speech but skips the brief brawl. During the bloodless (anime) Keith Green massacre, Sherry symbolically dies offscreen, and her disemboweled arm (manga) is replaced with stuffed bear.
