Arguably the easiest final boss ever.
How to beat.
1. Slash in four different directions, the fourth one will hit him
2. Move out of the way of his painfully slow slashes
3. When lightning strikes, do a skyward strike and zap him with electricity.
4. Do this three times, and on the final time, make haste to raise your sword before he charges you.
5. Slash with the electrified skyward strike, and use the ending blow.
Done.
