Also, you can catch useful items like Chaos Blades, Masamunes, Koga Knives, Chirijiradens, Javelin II and Excaliburs from the Ninjas in the level "HORROR". Just equip the "Catch" ability and find a group of level 90+ Ninjas. Especially useful if you missed getting the Masamune from Elmdor or the Javelin II from Nelveska Temple.
