Aliasing sencha_sadoru -> chiba_sadoru.
Aliasing chiba_saddle -> chiba_sadoru.
Reason: Going by his website, 千葉サドル is his name and SEN茶 is the name of his circle (though given the wiki, maybe he used to go by 千茶サドル in the past). Galge.com has romanized his name as "Saddle", but "Sadoru" appears in some of the illustrations on his own website, so I guess that is the preferred form of the two.
