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.
Crowning Moment of Heartwarming - After 15 books worth of misunderstanding and loneliness, the Grand Finale has Kitano saying "good morning"... to a cheer of other students waiting for him.
This part, where Ryoko finally realizes that Kitano is actually "A normal person".
Also goes to his father, when he hugs his love, finally showing an emotion after his The Stoic persona.
Hilarity Ensues - anything that is not a combat sequence and/or a crowning moment.
Ho Yay - Yuji Takehisa, after being "defeated" by Kitano, decides to follow him and be completely loyal to him. He tells Kitano that he's the only person he truly respects, and follows him around a lot (walking Kitano back home despite his own house being the opposite direction). He loses his cool whenever someone badmouths Kitano or tries to hurt him, and is shown acting as something of a chaperone to Kitano when Ikuno is around (even telling her it's so he can make sure she doesn't try anything funny).
