Heey :) I need to ask smthg abt an omake about the senba garasu you posted. I wanna ask whr did you watched this? I reli wud like to know thx :)

Is it the school uniform one? Then it would be under episode 3 of Sennen Makyou. Otherwise if you are talking about the omake of the football then it is under the OVA. Both could be seen in Animecrazy or Goodanime :) Hope it helps
