create alias pengwin -> ushimochi
create alias taku3949 -> takuro_(taku3949)
create alias takumi-macky -> bokuya
create alias pan_korokorokoro -> pan_korokorosuke
1st, I don't know whether the former is the old name or even correct in the first place. Both Twitter accounts have a different language, with "ushimochi" is mainly using Japanese, while "dr_penGwin" uses Korean.
2nd, stacc name -> current name + stacc name.
3rd, stacc name -> actual name.
4th, old name -> current name.
