We could also use 'Anko's Evolution' as a title. This implies a change in Anko in a positive and acceptable way, rather than using inappropriate or offensive terms.
The simplest way is to completely discard the inappropriate part. For example, we can just use 'Anko's Adventure' which is positive and engaging.
One more option could be 'Anko's Journey'. This title is general enough to cover various stories about Anko and doesn't involve any inappropriate content. It gives a sense of exploration and growth which is always a great theme for a story.
