Highlights of Kosu Fish
myfanator Editorial Department Published
Kosuyo's account is filled with selfies of less than 1 minutes. As an amateur, I have taken photos of myself and posted 17 photos and 14 videos. Works from 2026, 8, and 24 are recommended as the first 1 to watch.
Most of the footage is around 30 seconds long
Looking at the recent 12 films by length, 11 are around 30 seconds to the 1-minute range, with only the longest 1 videos exceeding 21 minutes. The number of reactions ranged from 1 to 4, with 21 minutes, 2 seconds, and 52 seconds both being the most at 4.
The only long runway is 21 minutes long.
Among the short videos, the 21 minutes and 2 seconds work is exceptionally long. There is no price for individual pieces; like other posts, you watch them in separate sections.
One tier, 2,400 yen
・3 bottles for 2,400 yen per month (about 800 yen per 1 bottles)
The paid tier is only 2,400 yen, and there is a separate plan where you can enter for zero yen. There is no system where you buy 1 videos at a time. The natural flow is to watch a few short videos on the free side and then switch to paid ones when you want to continue.
The scale of being chased by 34 people
He has 34 followers, and his total likes are 50. Among the 79 people holding up selfies, he ranks 49 st.
Differences from Yui, which has 185 stems
Yui is an account where you can watch 185 videos in a 2,980 yen tier and has a free entry point. Although there is a big difference in quantity, the ability to try short selfies from the free range is common to Kosuuyo.
It's suitable for those who like 'selfies' and 'amateurs.'
