Dinosaur Sanctuary Vol 9

From the Seven Seas Entertainment edition

HANG ON, HANAKO! Hanako, Enoshima Dinoland’s elderly Tyrannosaurus, collapses. The dinokeepers pray for her recovery, but the dino-vet tells them to brace themselves for the worst. As she sees Hanako growing weaker by the day, Suzume struggles to come to terms with dino-mortality. That's when a concerned Director Ogino steps in to tell her a story she hasn’t heard before—a story from Hanako's past.
