This article is about a/an Gurongi in Kamen Rider Kuuga.

Me-Biran-Gi (メ・ビラン・ギ)[1] is a piranha-like Gurongi who is member of the Me Group. He is given the codenames Unidentified Life Form #23 (未確認生命体第23号 Mikakunin Seimeitai Dai Nijūsangō) and B7 (B群7号 Bīgun Nanagō).

Assuming the form of a young man, Biran briefly challenged Zain after insulting him and his Zu. Biran later first made himself known to Kuuga when he attacks Zain for "stealing his turn". Once his turn began, Biran gets to kill off 180 people within a period of 2 days by attacking any form of water transportation and slaughtering the passengers single handily. He is capable of swimming, has an enhanced sense of smell, can bite with enough force to tear through concrete at a fast rate, and a cutter on each arm.

However, he is driven out of his game by the smell of blood overriding his senses, the police arrive to fight Biran until Kuuga arrives to fight him. But when Mighty and Titan Forms have no effect on the Me Gurongi, Biran is forced away when hit with a modified bullet. In spite of being injured, Biran was intending to make his quota to the very end.

When Ichijo manages to lure Biran out into the open, Kuuga kills him in Dragon Form by using the Splash Dragon.

In the World of Kuuga, Me-Biran-Gi is one of the leading Gurongi overseeing Gamio's revival alongside Go-Bemiu-Gi. After Tsukasa foils the Gegeru by shedding blood from Ai Yashiro, he is destroyed by Kuuga's Mighty Kick when he attempts to intervene in the battle between Kuuga and Decade. The World of Kuuga

At least one Me-Biran-Gi was part of a group of human-turned Gurongi created when they were exposed to N-Gamio-Zeda's miasma. Some were later absorbed by him in a last effort to defeat Kuuga and Decade. The remaining Gurongi died after Gamio was defeated. Transcendence
