Okay, I've tentatively put Hissatsu down as Certain Kill and ōgi as Hidden Skill. Onwards to finishing skillexpmessage
EDIT: Slight input needed. 槍に紅蓮の炎をまとわせ、横一文字の一閃で正面の敵を焼き尽くす。 I'm reading this as "With a spear clad in crimson flames, immolate the enemy infront (of you) with a flicker of a 'Yoko Ichimonji'"
I'm not one for martial arts but I think Yoko Ichimonji here refers to a move in several martial arts. Kendo comes to mind, specifically Iai-do, the art of drawing one's sword. I think it references the speed of a sword draw. 閃 means a flicker, a flash etc. Something quick. Anyone with a second opinion?
EDIT2: I'm gonna go ahead and post the completed skillexpmessage.pac here with the above translation. Post here for any second opinions.
EDIT3: I'm starting on Message.pac's characterexplain and charactername. Shouldn't take too long.
EDIT4: Here's the completed characterexplain and charactername. I was tempted to mess around with the names but decided not to. LOL. Anyways, I'm not sure which one to start on next so if anyone has a suggestion, post here.
EDIT5: Alright, I'm starting Message.pac's GuideMessage_JP.BTX. It looks like the text for the settings and stuff like that so it should not take too long.
