Viper

Viper (or ViperSean, Viperbro) joined the cast as the 'Explanations Man' in Issue 1, and joined the Bro-Rangers. He was turned against in Issue 7 for the perfectly legitimate reason of him never having played any of the Touhou Project games.

After being killed in Issue 10, he returned to the cast as a ghost in Issue 15 , and became aware that he could communicate with Scarbro. Since then he stays with Scarbro and helps her, since he doesn't like being alone.

Viper owns a Bag of Holding, an enchanted bag that can hold an infinite amount of objects inside it.

It is NOT a Man-Purse, and you'd do well not to question that fact.
