Aliasing ryohka -> ryouka_(suzuya).
Reason: They're one and the same however there are 2 pages left over that have not been tagged ryouka_(suzuya). Additionally many people know the artist under the name ryohka (due to the artist spelling their own name this way). This would aid searching danbooru as well as help join the straggling 2 pages with the rest.
