Saki

Her canonical story is that she is able to travel to any universe as long as she is not involved with the important characters of the games or stories she goes to. Due to this restriction she usually becomes friends with shopkeepers and faceless people but she always finds some ways to make her trips lively and enjoyable for herself. Her favourite place is a minecraft world where she is the mayor of a town called IceLake where she helps the villagers sort disputes and create community events for the whole town to enjoy.
