Impossible to Explain, Impossible to Understand (解説不可能意味不明, Kaisetsu Fukanō Imi Fumei) is the 31st chapter of the Gantz manga, written and illustrated by Hiroya Oku.

Cover PageEdit

A nearly naked Kei Kishimoto standing upright in a defensive position, wearing again only the top half of her Gantz Suit, while holding both an X-gun and an X-shotgun in her hands while wearing Gantz Suit Gloves.


The chapter begins in the mysterious room, right after "Sadako", Masanobu, Kayo and Ryota Sugihara have been transported there after their fatal car crash. The four biker gang members are there also, and all the new participants begin to panic, with Kei Kurono thinking to himself that it is just like how he and Kato acted when they first got to the room. Nemoto begins to act hostile, demanding an explanation as to what exactly is happening. Kato looks over at Kurono for confirmation, but he only shakes his head, signalling that they should keep quiet. He turns to Masanobu, but he reveals that he is just as clueless as Nemoto. Meanwhile, Sadako is in the background, not interacting with anyone.

Nemoto spots Kishimoto and he and two other bikers quickly surround her. She calls to Kato for help, just as the bikers begin to threaten Ryota's life for crying out for his mother, and he quickly gains the groups attention and explains their situation, despite Joichiro's dismay and protest. The Bikers are notably skeptical. Kato then asks Kurono to explain how the suits work, but he simply says that you need only put them on. He then asks Kurono if he killed the onion alien, but he replies that he didn't, and only sent it "up" with the gun Kato had.

Just as the bikers begin to bicker again, Gantz speaks up, shocking everyone present, other than Sadako, who is still hidden behind the door frame. Gantz reveals the next target on its screen, named the "Tanaka Alien", before releasing the group's weapons and suits. As the group begins to open their respective containers, the chapter ends with Kurono's dejected face, at the realisation that he does not have his suit.
