No. Just level one Tsuku up to lvl57, and then start pure-merging one by one (ONE AT A TIME), it should take about 7 or 8 merges to get the max bonus stats (200-100-100). If you do it earlier then it will take more than 8 pure merges to get the bonus. You could also start pure-merging in lvl55 since you got 15 copies of Tsuku.

Also, you'll need about 90000 spirit points to lvl up until 65.
