It doesn't match the name of any of the Adoulin-tier swords, so I'm a bit stumped. Abstract possibility it might be another language's way of reference Delive or even RMEs, but if he wasn't shouting with translate I don't know why he wouldn't feasibly know English equivalents.
Unfortunately there's not a whole lot you can do to spice up your BLU other than collect the various KIs and grind currency. Some NMs may have an okay niche for the job, but the job has some performance issues with lacking scaling to spell damage at the moment.
