If you push down the nice ones too much they will snap. This is what happens when you make Tomoko a pseudo-harem protagonist. Some pairings will rebel.
When you consider that Shinobu spent the majority of the entire series looking like an 8 year old girl, and most pictures of Shuten Douji maker her look like she's early teens at most, the comment makes sense. It wasn't saying this picture is of lolis. Common sense, people.
Am I the only one who feels sort of uncomfortable with Aerith paired with ANYONE? It's like doing a ship with Lavitz from Legend of Dragoon, or Shinji from Persona 3.
