Polite style with です and ます
Grammar: Colloquial and Casual Speech
です and ます mark the polite style: です is the polite “is”, and ます rides on the verb stem (行きます “go (polite)”).
In manga, politeness can be a form of characterization: who uses ます to whom, and when they stop, signals relationships.
Usage Notes
ます attaches to the ます-stem and conjugates as ました (past), ません (negative), ましょう (volitional). です follows nouns and adjectives, with でした and じゃありません as its past and negative.
い-adjectives take です directly (高

The Permanently Polite Character
Some characters never leave です・ます, which itself is the joke or the charm.

During an overnight school trip, a classmate tells a ghost story right before bedtime. While everyone else easily falls asleep, Sakura is too scared to close her eyes. The next morning, when Sakura washes her face, Tomoyo hands her a towel.
- さくら:
- 「ありがとーーー」
- “Thank you!”
- 知世
( : - 「きのうは ちゃんと眠
( れました?」- “Were you able to properly sleep last night?”
Although Sakura and Tomoyo are classmates and close friends, Tomoyo uses polite speech.
