Who is the character on Suguru's shirt? In Maji de Watashi ni Koi Shinasai!, Suguru is an otaku with an anime character on his shirt underneath his uniform:


I feel like this character is familiar, but all attempts to identify her have failed, so I'm now leaning towards the belief that she's just a made-up character drawn in a typical moe style. 

Is this a real character from some other source, or is it just a generic-looking moe character? Note that in the anime version, the character on his shirt looks slightly different, so in case they are actually different, this question is asking about the visual novel appearance above.
It's possible that it may be Yume Kuonji, the pink haired girl from Kimi ga Aruji de Shitsuji ga Ore de, the other visual novel from MinatoSoft, the maker of Majikoi. There's a lot of various character designs and the character on the T-Shirt could just be a stylized version of Yume. It's hard to tell from the screenshot above, but you can see in the other screen shot the ahoge, single strand of pink hair that's part of Yume's design.
