Straight: Bob is the idealistic leader of The Guardians of Gameland, who also consist of the jealous and brooding Tony, the nerdy Jack, the muscular Charlie, and the peaceful Alice. They are later joined by the mysterious Sam.
Each one is so capable on their own that it's a question why they're still together.
They each become so tired of being constrained to their roles and having to deal with each other, so they all leave on their own adventures, but they all become injured without support. Sam realizes he's going to die and leaves the group, Tony gets sick of playing second fiddle, Jack gets fed up with being The Load, Charlie gets tired of not being as smart as the others, Alice gets bored with being The Medic, and Bob grows weary of being a vessel for Character Development, leaving Yuki asking everyone not to leave.
