Toshio Igaaru
From The Heretic Knowledge Vault
Bani's Dad lives in Tsuirakushiti but spends most of his time in Kiyoka, which is presumably where he was originally from, assuming that he isn't the Farrelian half of Bani's parentage (given her Tsuirakuan surname and assuming that names in Tsuiraku are patrilinear, this seems unlikely). He is apparently an engineer or its magical equivalent, as he states in his first appearance that his work involves the devices that keep Tsuirakushiti afloat. Not much else is known about him yet, or whether there is any particular reason why he is suddenly back in Tsuirakushiti.
He's only been seen once so far, but he was heard on one previous occasion, when Sarine, Meji, Jon and Sara unexpectedly dropped in on the Igaaru family flat and Sara used her Time-ninja trick to check out the noise in the kitchen -- i.e., him. Well, wouldn't you scream under those circumstances?
Toshi, that's his name, and his wife were having difficulties in their marriage, when eight years ago she passed away for as yet undisclosed reason. He still misses her, despite the fact they would have separated if she had lived for a few more years. Sarine thinks this is a very elven thing to say.
