Greetings, lost children. I am Professor Kokonoe, genius scientist and ruler of the Sector 7 laboratory. …Well, OK, we aren't in the lab at the moment. This place can sort of be temporarily moved into the Boundary. Well, simply put, it's a mysterious room. A room where you can do anything you want. To be honest, it's a paradise for all those sad, little lost children who couldn't make it to the true ending. A sort of Avalon. If you're one of those nutbars who's all "I don't need help" or "I only want to unlock hidden stuff" or "I'll just look for a flowchart online", then you can piss off. … Very well. Lost child of the day… you may enter.
Help Me!! Professor Kokonoe (たすけて！！ココノエ博士) is an omake introduced in Blazblue: Continuum Shift. It takes place in a room somewhere within the boundary, where it is hosted by Kokonoe, who gives advice to the players on how to reach the true ending. This can be only accessed if the player had reached the bad ending.
