Context: it's the attack of an enemy stand! The senpai, Leone Abbacchio レオーネ・アバッキオ, has a plan to deal with it, but the kouhai, Giorno Giovanna ジョルノ・ジョバァーナ, thinks there's a better way. The senpai snaps:
kono joukyou dewa この状況では In this situation,
{senpai de aru} ore no meirei ga zettai da 先輩である俺の命令が絶対だ The orders of me, [who] {is the senior}, are absolute.
