A few things to Remember that the are all students at a school not ninjas where of course since the Akatsuki is a group they have things like knives and stuff a bit more about that whoud need to be explained -

The people
Akatsuki members and their weapons but also problems

Pain has anger problems but he uses knives
Konan don't really fight but she's the mother type in the group
Kakazu like in the show loves money and he uses rob but also an iron pipe
Hidan uses everything that he can use to cut not just himself but also others with and he's very over protected
Itachi uses mind games and a black sword he finds it fun to twist around with others
Kisame uses a sword
Tobi uses whatever he can get his hands on
Obito the same as Tobi both have problems with their heads which have resulted in a kid/child mind
Zetsu I don't know well eat people
Deidara has emotional problems but usually fight with a slingshot
Sasori uses knives but he got a problem with stress

Also chapter love part info
Kisame and Hinata still haven't told one another their feelings and bedside that Kisame doesn't have any weapons with him in the park.
