A character from Getsuyoubi no Tawawa. Kouhai-chan's senior coworker, who is also her unofficial self-appointed guardian from those who seek to exploit her when she's off-guard, especially when she's drunk.
His name is written ๅ ใใค, which is a pun on ๅ ่ผฉ ("senior, upperclassman") by way of how the second kanji is pronounced identically to the second half of ใชใใใค (oppai, meaning "breasts").
