Hayate the Combat Butler manga volume 43 features story and art by Kenjiro Hata.

As Hayate’s beach adventure reaches a climax, he finally reunites with his long-lost brother - to fight a possessed teacher! But our battlin’ butler’s troubles are only beginning. His quest to restore Nagi’s fortune takes him to her eccentric grandfather’s castle, where he has to overcome mazes, monsters, and an overly literal booby trap. Maybe the gang ought to go see a nice movie instead.
