[english -> japanese] need a kanji for a shirt

Need a Kanji for a shirt
me and my friends are going to japan shortly and we would love to have a matching white shirt with a Kanji on it

I'm looking for something that can be translated correctly but can also be "artistic", in both a letterary sense and a visual sense

The meaning i'm looking for Is something on the line of

- reaching a goal
- the end of a journey
- completing a monumental task
- finally ending a Wish you had in your Life

I don't know if it's possible but i would love a single kanji or maybe 2 tops, It would be awesome if it's even possible ahah

I love puns and such, and i know you can make those in Kanji (while mixing them?!?! idk tbh), so if someone has something funny or interesting in mind to add on this "serious" tattoo to make It both serious and funny, It would be awesome

like in One Piece, where there are names that have double meanings
it would be fun if some locals reccognize the pun and maybe laugh at it

I know this may be asking a lot, but i couldn't find anything on the internet that would make sense

Thank you all in Advance

edit: why was the post downvoted? did i do something wrong?
