These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Chapter 41 is chock full of it between Ciel and Masaya, of all people. For example:
Ichigo, Aoyama, and Ciel are all on a date.
"Aoyama saisd "hi" and ciel blushed and said "what?""
For some reason Ciel seems really... nervous around Masaya for no explainable reason.
Ciel turns into a tsundere around Masaya, saying things like "I didn't do it to help you. Its not like were friends or anything" and when Masaya asks why he's smiling, he screams "NOT BECAUSE OF YOU". Granted it wasn't because of him, but still.. defensive much, Ciel?
When Ichigo dissapears from the date suddenly, Ciel says to Aoyama, "oh god we are not on a date so you better go find your real date cuz this isn't going to work" and he feels "weird".
Tony and Winthorpe are gay/bi for Ciel, and a lot of queer things seem to happen between them.
Ciel begrudgingly giving Tony his jacket because he's cold... not to mention the cliche BL scene of two guys alone in a classroom together.
Tony telling Ciel his long hair is cute, and later asking if he has a girlfriend, then laughing nervously and saying "who needs girls?"
Ciel constantly thinking of Tony or complaining about him, mixed with the frequent utterances of his name may count.
Ciel telling Tony "i am hard for you", though it seems to be accidental.
What The Hell, Costuming Department?: Among many odd outfits, one that's particularly odd (even questioned in the story) is Mint's 'beach' outfit in chapter 5. She wears a skimpy navy two-piece... underneath a giant blue ball gown with bows all over it, which her dog has a matching bow to. Some other odd choices include:
Zakuro's space outfit, which seems like it would be completely useless in space.
Otachi's cafe uniform, which is black with gold and red trim, chains, combat boots, martial arts gloves (not pictured), and a flame design on the sleeves. The cafe he's working at? Cafe Mew Mew, the girliest, pinkest cafe to ever exist, which previously had an all female waitress staff who wore bright, colorful, and frilly maid uniforms.
Many of Otachi's outfits are impractical for fighting, but the strangest one was when he and Ichigo were sneaking around to find Mint in chapter 3. She had a black cat suit, sure, but he had a black wolf suit with finger-less gloves, red lining (which won't help you blend in), and CHAINS. Chains are too noisy to sneak around with.
