Nagi- You can get her after few event in the dungeon. (apparently she is lost on the way to somewhere n ended up dungeon)
after few event, she will 1st appear as customer (event) n finally gave her card.
battle - attack range, 1 straight line. better range than Louis (or watever his name). since her attack is a straight line, kinda hard to hit the bee.

Elan - Got him after few town event.
battle - kinda like Nagi but shorter range. can do 2 hit combo. able to dash (straight only). same problem with Nagi, its da bee.

Caillou - Need to reach certain merchant level (taking order in advance skill). He will show upp asking for charred lizard, Slime Liver n cant remember wat de.
since there is not time limit to get the item for him, he will come once awhile even after u fail to met his demand when u appear. other 2 are easy to get, Slime Liver, u had to get it from King of Slime.
Battle - since hes a mage, his attack range is like Elan, but worse. he can charge up his attack (fire ball projectile), but while chargin, hes immobile. every normal attack add SP, so dun be afraid of using his skill.

Tiella - Like Charme, she appear on the 3rd final dungeon where u had to face her.
Battle - range attack, her normal attack are chargeable,
uncharged: mid range attack
lvl 1: long range attack
lvl 2: 3 split arrows attack
lvl 3: 5 split arrows attack
lvl 4: 5 split arrows attack + 1 behind
lvl 5: 5 split arrows attack + 3 behind
