The predicament with Hebi was very large... If Medusa found out about the infiltration, then this whole proposal would be off and she wouldn't guide them through Arachne's Base, which was absolutely crucial... Hebi would have to remain hidden until all of this blew over... But if Hebi was within Shibusen, he was constantly eligible to be found out by Medusa, making the problem even greater than it already was..
"... I know all of this, Hebi-chan... The only thing for you to do is to take a temporary leave from Shibusen until Medusa and her teams set off for Baba Yaga's Castle... You must take any and all possessions you own that are within Shibusen and take them with you... In fact, I am sending you on a special mission, Hebi... You are the only one who knows where Medusa's hideout is. I want you and your weapon to go in and gather up any and all information that you can... Since Medusa and her party will be here. Do not depart until you are sure that everyone of Medusa's party has left... Take this mirror so that I can contact you when they are on their way back."
Shinigami would give Hebi a small hand mirror for his travels.
"... Until they are all here, I must ask you to hide in the depths of Shibusen. Do not make a sound until I give the okay, Hebi-chan."
This was a serious matter and must be followed to the T if it were going to be executed correctly.. and Shinigami was well aware of this. This mission was deadly... And the Baba Yaga Mission was even more deadly... Finally, Shibusen was starting to take action against the rogue witches again, and soon, they would be with... Asura.
