Can you post a list of your current weaponry (plus skills and enhancement levels), and magatama?

One important thing you probably missed: Odin is hard to beat at this level, unless you already have a partner from the 'Special' tab, and use it in Vanguard mode to kill Odin.

You get access to a mission each to get Izuma and Gennai once you cleared Kyoto's part of the main story, you only need to have beaten Odin once for that even if you did not do well.
You can also currently get one from the one-off even for this mount, AND Hound Dog mount from the Redux event; you can use both Special and Mount simultaneously, and the mount actually fight as well, so that will also make Odin easier to beat.

If you need help to get the mount, ask someone to help; I have not tried, but I do not thing that the 2 dungeons required are solo only (someone else replies if I am wrong on that, please).

As for getting better weapon, just farm any of the dungeons at the highest map you can beat, until a good one drops, simple as that...
Highest attacks is not automatically the best weapon, what skills are on the weapon matter a lot.
To beat Gennai's lab, for instance, you will want to use a range weapon even if you do not usually use one (to 1-shot the 2 Kameras early on, and to keep Gennai alive until the bosses room); that means having a long range attack skill with high damage.
