I went to collect the opinion of 5 different persons on the subject MR/honoka, and this was so hilarious i had to put it here :
-Personne 1 (female, DOA very "casual" player) : "They do look like sisters, but the pink haired one look older, and they don't have the same noes." (me : ? what the hell, this is the same noes man haha)
-Personne 2 (female, didn't know of DOA) : "The hell, they both look like fake asian idol, with the same shitty plastic face". I then told her MR's origins and she answered : "LOL that moe plastic bullshit is not asian ? She is 18 ? LOL ! Are you kidding me ?! She just have the exact same fake plastic face than the pink haired crap. Well, can't really help you, all the Japanese idolshit look the same to me". (she killed me XD)
-Personne 3 (female, played DOA with me sometime) : "Oh man, what are you saying ! They don't resemble each other at all ! MR is a kid, and she is a grown girl. If you ask me, i'll say she look a lot more like Kasumi, but she is far from a copy. Well, I'd love to try her !"
-Personne 4 (male, never played DOA but know the universe, including MR) "Well, for a supposed new character, she is not SO new... She clearly look the same than MR, maybe swap face ? IDK, but to me they look quite the same."
-Personne 5 (male, never played DOA, but played NG) "I don't know why people are ranting for. Saying they look the same is absolutely wrong. The two face are pretty different and the pink-haired new girl look good. You have to be blind to not see that those faces model are different, look at the eyes man. Yeah, definitely a useless debate, they have different face."
To make worth-using stats, i'd love to use a +100 000 opinions randomly selected in a representative population, but well... That was hella funny to see how different those answers were. I guess the subject "do they look alike" is pretty subjective...
